The Timeline

Fifty Years.
One Facility.
Final Phase.

Beagles have been bred at this Cambridgeshire site for half a century — up to two thousand a year, as widely reported, most sold for laboratory toxicity testing at around sixteen weeks old. The campaign that has worked to end that has reached its final phase. This page is the public record of how we got here — eight phases, in order: every conventional route exhausted, an open letter MBR Acres chose not to answer, and a September spent marching in step with America. Then the part that needs you.

Save the MBR Beagles is an independent UK civic campaign calling for the lawful closure of MBR Acres through licence revocation, parliamentary action, and public pressure on the laboratory supply chain.

Camp Beagle. Five Years At The Gate.

The world's longest continuous animal-rights vigil. Outside MBR Acres since June 2021. Documenting every vehicle in, every vehicle out.

And counting.

Camp Beagle has been the on-the-ground witness for more than five years. Logging deliveries to Charles River, Labcorp and Sequani. Documenting the inside of an industry that has never wanted to be seen. Lawful, present, persistent. Camp isn’t going anywhere — and the longer it stays, the harder MBR’s position becomes.

We Have Marched. We Have Been Counted.

More than a decade of demos, vigils and national days of action at MBR's gate and across the UK.

Camp Beagle and a range of independent activist groups have held lawful presence at this site for over five years. National days of action have brought hundreds to the gate, repeatedly. This is not a moment of public attention — it’s a sustained civil-society effort that has refused to go away. And still: the facility breeds up to 2,000 puppies a year.

We have marched. We have gathered. We have been counted. Repeatedly. The gate has not opened — so we keep walking to it.

Same parent. Both sides of the Atlantic.

The world is closing in on the laboratory-beagle industry.

MBR Acres Ltd is a UK subsidiary of MFG International, which sits beneath Marshall BioResources in New York. This is an American multinational running a British beagle farm.

The same Marshall group runs MBR New York in the United States, currently the subject of an ongoing campaign by Save the Dogs USA. Separately, another US beagle-breeding facility — Ridglan Farms in Wisconsin, an independently-owned company — has agreed to close for good. Every remaining beagle is being released to rescue — more than 2,000 dogs in total — ending a multi-year US campaign in victory.

The picture is unmistakable: the laboratory-beagle industry is shrinking, on multiple fronts, in multiple countries, at the same time. Closing down MBR Cambridgeshire isn’t a UK-only story. It’s the British front of a global push — and that push is winning ground year on year.

BLOCKED

Parliament Heard. Government Refused.

Westminster Hall, 27 April 2026. MPs from Labour, the Conservatives, the Liberal Democrats, the Greens and the Independent benches spoke in favour of ending dog testing. The minister offered £75 million for research and a vision statement. That was it.

“Any move to end animal testing would be welcomed by many of our constituents.”

— Irene Campbell · Lab · North Ayrshire and Arran — APPG chair · Opening the debate

“It would be extremely naive to believe that that legislation was introduced for any reason other than to address the presence and actions of Camp Beagle.”

— Ben Obese-Jecty · Con · Huntingdon — MBR Acres’ own local MP · On the KNI Statutory Instrument

“When we cannot be sure that it is effective, testing on animals is not science — it is just violence.”

— Adam Dance · LD · Yeovil

“Over 90% of drugs that appear safe and effective in animals never make it through to approval for human use.”

— Adrian Ramsay · Green · Waveney Valley

“The system is failing both animals and humans. We have the evidence, we have the technology, and we have the public backing.”

— Adrian Ramsay · Green · Waveney Valley

“Scientists doing tests on mice just in case they spot something fascinating seems completely wrong.”

— Kerry McCarthy · Lab · Bristol East

“Some of us voted against the effort to quell protests against the site; it seemed a case of using a sledgehammer to crack a nut.”

— Kerry McCarthy · Lab · Bristol East · On the vote to criminalise Camp Beagle

“I am wholly opposed to animal testing in all its forms; I believe it should be phased out across the board to the maximum extent possible.”

— Bradley Thomas · Con · Bromsgrove

“A 35% reduction five years away is not ambitious enough, and it has not been put on a statutory footing.”

— Gideon Amos · LD · Taunton and Wellington

“Animal testing should be ended as soon as possible and this debate should spur the Government into doing a lot more.”

— Gideon Amos · LD · Taunton and Wellington

“The Government have authorised the use of more than 6.5 million animals in experiments over the coming years.”

— Olly Glover · LD · Liberal Democrat spokesperson

All quotes verbatim from the Westminster Hall debate on e-petition 736578, 27 April 2026.

Read the full Hansard transcript

The government’s response — in their own words

Ian Murray, Minister of State (DSIT). Not the Home Office.

“We want to replace animals in science wherever possible.”

“Backed by £75 million of funding to accelerate alternative methods.”

“Use of dogs in experimental procedures decreased by 29% compared with 2023.”

“A world in which the use of animals in science is eliminated in all but very exceptional circumstances.”

What the minister did NOT say

  • · No mention of MBR Acres.
  • · No statutory target with a date.
  • · No response on the forced swim test.
  • · No response on the KNI regulations targeting Camp Beagle.
  • · No engagement with the 121,854 petitioners’ actual ask: statutory diversion of funding to non-animal methodologies.

Parliament heard us. Hansard records it. The government will not act. That is where the conventional route ends.

An Open Letter To MBR Acres.

A direct, public ask: meet us. Talk. Negotiate a peaceful close-down — the Ridglan model. Sent 20 June 2026. The four-week window closed on 19 July 2026. No reply.

Sent 20 June 2026

To the Directors, MBR Acres Ltd

We are writing to offer MBR Acres a way out.

In 2026, an American beagle-breeding facility of comparable scale — Ridglan Farms in Wisconsin — agreed to close for good, releasing every remaining beagle to rescue — more than 2,000 dogs in total. It did so after a multi-year public campaign, peacefully, on a negotiated basis. We are writing to ask MBR Acres to do the same: meet, talk, and agree the peaceful end of this facility. That is the entirety of our ask.

The case against MBR Acres has been settled in the public mind for years. The 121,000 signatures presented to Parliament on 27 April 2026 did not start this conversation. They were the most recent entry in more than a decade of petitions, debates, letters and demonstrations, each one returning the same answer from the British people: this must end.

[The full letter continues. Read it below.]

The deadline passed

We asked MBR Acres for a substantive response within four weeks. The window closed at midday on 19 July 2026. Nothing came back — not a refusal, not a holding line, not an acknowledgement. The letter, and the silence that answered it, are both on the record.

Every week of that silence is a week inside for the dogs. Puppies are still being born into the facility; adolescent beagles are still reaching the age — around sixteen weeks — at which they are loaded into vans and sent to toxicity laboratories. So the pressure moves back outside the gate, where it has always been loudest.

The route was visible. They chose silence. We choose the street.

06
COMPLETE

Out Of Silence. Onto The Street.

MBR Acres chose not to answer. So we took the question to the people who license it, and to the gate itself.

6 August 2026 · Westminster

The Home Office

Around fifty supporters gathered peacefully outside the department that licenses MBR Acres — many of them campaigning for the first time. Four people spoke, including whistleblower testimony from inside the industry, and leaflets went to staff and passers-by. Leicester Animal Rights Group stood with us.

6 September 2026 · Wyton

A Vigil At The Gate

Led by campaigner Beth, supporters gathered outside MBR Acres to remember the thousands of dogs who have died inside. Poems were read, flowers laid and stones painted; Ben Richardson sang a song written for the puppies, and there was a silence for the dogs still behind the fence. They are not numbers.

Read the write-up

One demonstration at the regulator’s door, one vigil at the breeder’s. Both peaceful, both public — and both the warm-up for September.

Two Countries. One Company.

September 2026. While Americans walked 207 miles to Marshall BioResources, we marched in London, Harrogate and Huntingdon — and filled every day in between.

12–26 September · USA

The March to Abolish Animal Testing.

On 12 September the March for Animals set out from Albany, New York on a 207-mile, fourteen-day walk to the gates of Marshall BioResources in North Rose — the company that owns MBR Acres. Every UK march and walk in this phase was timed to it: we set off on the day they set off, and reached our gates on the day they reached theirs.

The ground is shifting over there. The NIH has closed its internal beagle laboratory and is backing the rehoming of research animals, and Marshall BioResources is now working with rescues to rehome beagles from its New York site. Another future for these dogs is possible — and it is the precedent we are asking for here.

Harrogate marched the same day, and met a town centre that mostly had no idea beagles are still bred for testing.
  • 13–25The days in between: supporters claimed them with walks of their own — Mansfield, Holkham, Biggleswade, Maidenhead, Rosehearty, Leamington Spa, Bamburgh, daily leafleting at Margate station and more — so that every day the Americans were on the road, somebody in the UK was walking too.
  • 26 SepHuntingdon: more than 200 people walked from the station to the gates of MBR Acres, arriving as the March for Animals arrived at Marshall BioResources — one company, one afternoon, two countries. 207 yellow ribbons went up on the trees beside the site, one for every mile walked in America. The march made the campaign’s first TV interview, on That’s TV Cambridgeshire.

Fifteen days, two countries, one company. They will have noticed.

CURRENT FOCUS

The Future?

Bigger than one facility — and it needs you in it. Sign the petition, come to the next event, and find your way to help.

MBR Acres is one front in a much larger fight. Closing it would be a landmark — but it is not the finish line.

Our aim is to bring the strands of this movement together — campaigners, fosterers, vets, lawyers, MPs and ordinary people — behind one shared goal: an end to beagle breeding and testing in the UK, and ultimately an end to animal testing in this country altogether.

No single group gets there alone. Camp Beagle at the gates, the supply-chain campaigners, the lawyers, the letter-writers, the person running a stall in their home town on a Saturday morning — every part matters, and it works best when it works together.

The science has moved. Public opinion has moved. The law can follow — if enough of us keep pushing, in the open, together.

Where this is heading

  • 01The lawful closure of MBR Acres — an end to beagle breeding at Wyton.
  • 02A UK-wide phase-out of dog testing with a real timeline, not a vague aspiration.
  • 03Ultimately — an end to animal testing in the UK, replaced by the modern, non-animal science that already exists.

Proof it can be won

Ridglan Farms beagles freed as the facility closes for good

Wisconsin, 2026 — Ridglan Farms, a facility of comparable scale to MBR Acres, agreed to close for good and release every remaining beagle — more than 2,000 dogs. What looked impossible became inevitable once the movement refused to look away. That is the template.

Our preference is peace, and our method is the open, lawful, stubborn kind of pressure that has already emptied facilities elsewhere. We won’t go away — and we are stronger together.

The receipts

The full chronology.

Every documented date in this story — the breeding, the law changes, the trials, the debates, and the campaign. All of it sourced on this site: see the facts, the law and the trials.

1970s–2018

  1. From the 1970s

    Fifty years of breeding at Wyton

    Beagles are bred for laboratories at the Cambridgeshire site for half a century — through its Interfauna and Harlan eras, before Marshall BioResources’ UK subsidiary takes over in January 2018.

  2. July 2012

    Green Hill seized — Marshall’s Italian beagle farm

    After years of protest and complaints, Brescia prosecutors seize Green Hill in Montichiari, the Italian beagle farm of Marshall BioResources. Around 3,000 beagles are placed with the charities LAV and Legambiente and rehomed. Trial evidence later recorded 6,023 dog deaths there between 2008 and 2012. Details→

  3. March 2014

    Italy bans breeding dogs for experiments

    Legislative Decree 26/2014 bans breeding dogs, cats and primates for use in experiments in Italy. Green Hill can never reopen. The UK has no such ban.

  4. 23 January 2015

    Green Hill staff convicted of animal cruelty

    The Court of Brescia convicts three senior Green Hill staff — the executive manager, the director and the vet — of animal abuse and unnecessary killing of animals, with sentences of 12 to 18 months. Upheld on appeal in February 2016; made final by Italy’s Court of Cassation in October 2017. The precedent: a beagle farm can be emptied, closed, and its operators held to account. Details→

  5. January 2018

    Marshall BioResources takes over Wyton

    MBR Acres Ltd — the UK subsidiary of the US group Marshall BioResources, incorporated in April 2017 — takes over the Wyton beagle-breeding site from previous owners including Harlan Laboratories, as a 2021 High Court judgment records. The facility is now known as MBR Acres.

2020–2022

  1. 2020

    Full capacity: ~2,000 puppies a year

    The Wyton site reaches full operation — up to two thousand beagles reported bred each year, most sold to laboratories at about sixteen weeks old.

  2. June 2021

    Camp Beagle begins

    A continuous, lawful vigil starts at the gates of MBR Acres — it has not left since, and is described as the longest continuous animal-rights protest in the world.

  3. 2021

    4,016 procedures on beagles in UK labs

    Home Office statistics for 2021 record 4,016 procedures on beagles in British laboratories in a single year.

  4. From 2021

    The policing bill starts climbing

    Cambridgeshire Police begin a spend on policing MBR Acres protest activity that passes £2.1 million by 2026.

  5. 2022

    Petition passes 100,000 signatures

    A parliamentary e-petition on the commercial breeding of animals for laboratories passes 100,000 signatures (around 102,000 in all), the threshold at which Parliament considers it for debate.

  6. June 2022

    First open rescue — 5 beagles

    Five beagles are carried out of MBR Acres in daylight. The CPS initially drops all charges, then resurrects them years later.

  7. 20 December 2022

    The largest open rescue — 18 beagles

    Supporters of Animal Rebellion (now Animal Rising) enter MBR Acres and take twenty puppies. Police recover two; the other eighteen are never returned. Eighteen people are later charged with burglary — the cases behind the 2025–26 Crown Court trials.

  8. 23 December 2022

    Love and Libby returned

    Two of the puppies, intercepted by police, are handed back to MBR Acres. What happened to them after that has never been made public.

2023–2025

  1. 16 January 2023

    First Westminster Hall debate

    MPs debate the e-petition on commercial breeding for laboratories in Westminster Hall after it passes 100,000 signatures.

  2. 2023 onwards

    65+ companies cut ties

    Under sustained, lawful public pressure on the supply chain, more than sixty-five companies walk away from MBR Acres.

  3. 2024

    Half a million signatures

    Petitions across platforms collectively pass 500,000 signatures.

  4. October 2025

    Ridglan agrees to give up its licence

    To avoid prosecution for animal cruelty, Ridglan Farms in Wisconsin — the closest US equivalent to MBR Acres — agrees with a court-appointed special prosecutor to surrender its state licence to sell dogs, effective 1 July 2026. Details→

  5. November 2025

    ASRU audits MBR Acres

    The Home Office regulator carries out an announced inspection of MBR Acres and, ministers later tell Parliament, records no critical or major findings — only minor ones such as surface rust and a loose drain cover. The audit MPs would question in the House.

  6. November 2025

    Government publishes its phase-out strategy

    “Replacing Animals in Science” promises to phase out animal testing “in all but exceptional circumstances” — with no statutory targets attached.

  7. 16 December 2025

    Trial 1 — Cambridge Crown Court

    Five defendants convicted of burglary over an open rescue; suspended sentences and a conditional discharge. No custody.

2026

  1. 12 January 2026

    Trial 2 — first open-rescue acquittal in UK history

    A Cambridge jury unanimously acquits four defendants. For the first time, a UK jury says an open rescue of laboratory animals was not dishonest.

  2. 14 January 2026

    MPs approve the “national infrastructure” law

    The House of Commons approves, by 301 votes to 110, regulations adding “life sciences infrastructure” — animal testing facilities, including a commercial dog breeder — to the Public Order Act 2023’s Key National Infrastructure offence. On 4 February the House of Lords votes down a motion to stop them. Details→

  3. 3 February 2026

    Trial 3 — Peterborough Crown Court

    Four defendants convicted of burglary after around five hours of deliberation.

  4. 12 February 2026

    The KNI law takes effect

    From this day, “interfering” with MBR Acres — a dog breeder now legally classed alongside power stations and hospitals — carries up to 12 months in prison and an unlimited fine.

  5. 24 February 2026

    First arrests under the new law

    Two campaigners are arrested at MBR Acres under the KNI offence — the first in the country.

  6. 2 March 2026

    Judicial review filed

    Lawyers for Animals and Camp Beagle campaigner Maria Iriart (represented by Bates Wells) file High Court proceedings arguing the KNI regulations are unlawful and breach ECHR Articles 10 and 11 — free expression and peaceful assembly.

  7. 9 March 2026

    Trial 4 — second acquittal

    A Peterborough jury acquits all five defendants, including Animal Rising director Rose Patterson, after three days of deliberation. Chris Packham gives a character reference.

  8. 26 March 2026

    Trial 5 — and the bleeding licence concession

    Three defendants convicted by 10–2 majority over the June 2022 rescue. In the process, the prosecution concedes on the record that MBR Acres holds a licence to bleed dogs under terminal anaesthesia.

  9. 18 April 2026

    Ridglan Farms, Wisconsin — the movement escalates

    Over 1,000 peaceful activists converge on Ridglan Farms, the closest US equivalent to MBR Acres. Deputies respond with tear gas, rubber bullets and flashbangs; 25 are arrested, including four attorneys.

  10. 24 April 2026

    Class action over the Ridglan policing

    A federal class action is filed in Wisconsin over the policing of 18 April.

  11. 27 April 2026

    Second Westminster Hall debate

    Petition #736578 to end testing on dogs and other animals — 121,854 signatures when it closed three days later — is debated. Labour, Conservative, Liberal Democrat, Green and Independent MPs speak for ending dog testing. The local MP, Ben Obese-Jecty, tells the House it would be “extremely naive” to believe the KNI regulations were introduced for any reason “other than to address the presence and actions of Camp Beagle”.

  12. 29 April 2026

    Ridglan agrees to release 1,500 beagles

    Big Dog Ranch Rescue and the Center for a Humane Economy secure about 1,500 of Ridglan’s beagles for rescue — and the US House Appropriations Committee passes a cross-party amendment directing the USDA to review breeder licences where state licensure is lost.

  13. 1 May 2026

    The Ridglan transfers begin

    The first of the 1,500 beagles leave Ridglan for rescue.

  14. May 2026

    Lush Prize 2026

    Camp Beagle is commended in the Public Awareness category of the 2026 Lush Prize, awarded in London from a £250,000 fund for work to end animal testing.

  15. 15 June 2026

    Ridglan agrees to close for good

    Big Dog Ranch Rescue announces a deal for the permanent closure of Ridglan Farms and the transfer of its last 475 beagles — more than 2,100 dogs rescued in all. Its licence surrender takes effect on 1 July. Proof that a breeder of MBR’s scale can be emptied by lawful, relentless public pressure. Details→

  16. 20 June 2026

    The open letter is posted

    Dated and sent by recorded delivery to MBR Acres, its parent companies, customers and the Cambridgeshire authorities — proposing a negotiated, peaceful end to breeding at Wyton, including an offer to buy the remaining dogs.

  17. 21 June 2026

    The letter goes public

    Hand-delivered in person and published in full on this site at midday. Thousands add their names.

  18. 9 July 2026

    Dog use rises again

    Home Office statistics for 2025 record 2,889 experimental procedures on dogs in Great Britain — up 9% on 2024 — among 2.54 million procedures on animals in all. Details→

  19. 19 July 2026

    The response window closes — no reply

    The letter gave MBR Acres four weeks for a substantive reply. None came. The silence is now part of the public record, alongside the letter itself. Details→

  20. 29 July 2026

    High Court allows a challenge to the KNI law

    The High Court grants Animal Aid permission to bring a judicial review of the regulations that made “life sciences infrastructure”, MBR Acres included, Key National Infrastructure. Details→

  21. 6 August 2026

In short

The timeline: questions

How long have beagles been bred at MBR Acres?
Beagles have been bred for laboratories at the Wyton site in Cambridgeshire, now called MBR Acres, for around fifty years, through its Interfauna and Harlan eras. A 2021 High Court judgment records that the site was owned by other companies, including Harlan Laboratories, until January 2018, when MBR Acres Ltd, a subsidiary of the US group Marshall BioResources, took it over.
How long has Camp Beagle been outside MBR Acres?
Camp Beagle, a continuous protest camp at the gates of MBR Acres in Wyton, Cambridgeshire, was set up in June 2021 and is still there as of October 2026, more than five years on. In 2021 the High Court declined to remove the camp, imposing an exclusion zone around the gates instead. It is an allied campaign; Save the Dogs UK is independent of it.
What happened at the Westminster Hall debate on 27 April 2026?
On 27 April 2026 MPs debated e-petition 736578, "End testing on dogs and other animals", which closed on 30 April with 121,854 signatures. Labour, Conservative, Liberal Democrat, Green and Independent MPs spoke. Huntingdon MP Ben Obese-Jecty said it would be "extremely naive" to think the KNI protest regulations were made for any reason other than Camp Beagle. The Government pointed to its November 2025 strategy and £75 million for alternatives. Read the debate.
What is the KNI law and how does it affect protest at MBR Acres?
Regulations under the Public Order Act 2023, approved by MPs 301–110 on 14 January 2026 and in force from 12 February 2026, added "life sciences infrastructure" to Key National Infrastructure. Interfering with sites such as MBR Acres can now carry up to 12 months in prison and an unlimited fine. On 29 July 2026 the High Court gave Animal Aid permission to challenge the regulations. See protest laws.
Did MBR Acres reply to the open letter?
No. Save the Dogs UK sent MBR Acres an open letter dated 20 June 2026, published it on 21 June, and asked for a substantive reply within four weeks, proposing a negotiated, peaceful end to beagle breeding at Wyton. The window closed on 19 July 2026 with no reply, refusal or acknowledgement from MBR Acres. Read the letter.
What happened to Ridglan Farms?
Ridglan Farms in Wisconsin, the closest US equivalent to MBR Acres, agreed in October 2025 to surrender its state licence to sell dogs from 1 July 2026 to avoid animal-cruelty prosecution. In April 2026 rescues secured about 1,500 of its beagles, and on 15 June 2026 it agreed to close for good, with more than 2,000 dogs going to rescue in all. See Ridglan.
What were the September 2026 marches?
In September 2026 Save the Dogs UK marched in solidarity with the US March to Abolish Animal Testing, a 207-mile walk from Albany, New York, to Marshall BioResources, owner of MBR Acres. Around 300 people marched in London on 12 September, supporters filled the days between with local walks, and more than 200 walked from Huntingdon to the gates of MBR Acres on 26 September.
