To MBR Acres.

Dear Directors,

We are writing to propose a voluntary negotiated resolution to the long-running public controversy surrounding the Wyton facility.

This letter is an invitation to open negotiations. It is not a demand, and nothing in it is conditional on any threat of unlawful action. Any continuing public advocacy described here is lawful, would continue independently of this letter, and is not offered or withheld as a bargaining chip. We confirm that this letter is sent without prejudice to any rights or positions of either party and is intended solely to explore a mutually agreeable commercial resolution.

We are writing to make a serious commercial offer to purchase the entire remaining breeding stock of beagles at the Wyton facility at a premium above market value. This would allow MBR Acres Ltd to realise immediate full value on current inventory, avoid ongoing breeding and maintenance costs, and redeploy resources elsewhere in your business. We propose this as a straightforward, arm’s-length commercial sale of animals, with no admission of any kind regarding your operations or the broader use of animals in research. We respect that your facility operates lawfully under Home Office licensing.

In April 2026, an American beagle-breeding facility of comparable scale — Ridglan Farms in Wisconsin — agreed to release its 1,500 dogs to rescue and wind down its operation. It did so after a multi-year public campaign, peacefully, on a negotiated basis, with the receiving costs underwritten by a coalition of welfare organisations. We are writing to invite MBR Acres to consider doing the same: meet, talk, and agree the peaceful end of this facility and the release of the beagles — in whichever way we can agree, including by direct purchase. That is the entirety of our ask. The rest of this letter is the reason we believe you may agree.

We emphasise that this is a good-faith commercial proposal and is not intended to cause any commercial harm or reputational damage beyond what has already arisen from lawful public discussion of the issues. Our coalition is prepared to fund a purchase price to be negotiated, together with reasonable costs associated with an orderly transition, including staff support packages. We are willing to engage independent valuators mutually agreed to ensure fairness.

Before anything else, we should say plainly why this campaign exists. It exists because of the dogs. Beagles are bred at Wyton for one purpose: to be sold to laboratories, dosed with experimental substances, and ultimately killed and dissected. A beagle born inside this facility will, in the ordinary course of things, never feel grass under its feet, never be taken for a walk, never be named by someone who loves it, never know a single normal day of the life a dog is meant to have. Born indoors, kept indoors, and removed only to be experimented on. That is the entirety of the life on offer to them. These are strongly held views based on our assessment of the available information and public records.

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.

On the floor of that debate, eleven Members of Parliament — Labour, Conservative, Liberal Democrat and Green — spoke against the continued use of dogs in laboratory testing. They were not lobbyists. They were not activists. They were elected representatives, on the public record, speaking on behalf of their constituents and ours. The Government’s reply ignored them. It ignored the petitioners. It did not engage with what was being asked. It is, in our view, the moment the conventional democratic route on this issue ran out. We respect the Government’s position and regulatory framework.

Outside your gate, Camp Beaglehas held a continuous, lawful vigil since June 2021 — almost five years without a single day off. Every vehicle through your gate has been documented. Every customer’s delivery, photographed. That lawful documentation has continued for almost five years and, on current trends, is likely to continue. We record these facts as part of the public record and make no implication of any unlawful activity.

On two occasions — at Cambridge Crown Court, and again at Peterborough Crown Court — juries declined to convict defendants who had entered the facility. That is not an activist’s opinion; it is a matter of public court record. We draw no threat from that, and we make none. We record it only as a measure of how this facility is now regarded by ordinary members of the British public. We do not condone unlawful entry and emphasise that all our activities are and will remain lawful.

What those juries saw, the public could not. Inspection reports of your facility were kept from view until the Information Commissioner ruled the Home Office had no lawful basis to withhold them. We note these public records without allegation of wrongdoing.

We are not writing to ask the British government to act. They have already had their chance, repeatedly, in public. We are writing to you, MBR Acres, directly. Here is what we propose:

1. A meeting, in good faith, between the directors of MBR Acres Ltd and representatives of this campaign, to discuss the terms set out below. Time, place and legal representation entirely of your choosing.
2. The purchase of the remaining beagles at the Wyton facility — currently estimated at around 1,500 — by this campaign and its funding partners, at a fair commercial price agreed between our representatives and yours. From your accounts’ perspective this can be treated as any other contractual sale of stock: a single transaction, completed in full, on terms you would recognise from any other customer. The dogs leave your books and go to vetted rescue organisations that have already signalled willingness to receive them. We will coordinate the receiving side. The transaction can be quiet, professional, and dated to suit you and can be at market value, together with reasonable transition costs.
3. A commitment to cease all new breeding at the Wyton facility and to wind down the operation in an orderly way. We propose a phased approach: immediate purchase and removal of current stock, followed by a mutually agreed period during which no new breeding occurs, allowing an orderly wind-down of the specific dog breeding operation.
4. Optional/Voluntary disclosure of unabbreviated company accounts and all current Animals (Scientific Procedures) Act 1986 licences relating to the Wyton operation. This is requested only as part of a voluntary settlement; nothing in this letter seeks disclosure under threat, and this point falls away entirely if the wind-down agreement is reached on other terms.

We recognise that a campaign about a facility necessarily concludes when the facility itself does. If the Wyton site ceases breeding and closes, the subject of this particular campaign no longer exists. We state that simply as an observation about cause and effect — not as anything offered in return for, or conditional upon, agreement. Our concerns about the use of dogs in laboratory research in the United Kingdom more broadly are separate questions, for separate conversations, which we will continue to pursue through lawful, public means. Any agreement would include strict mutual confidentiality and non-disparagement clauses. Neither party would comment publicly on the transaction beyond a neutral joint statement. We would undertake to cease all facility-specific campaigning upon completion of the transfer.

This is not a hypothetical ask. Ridglan Farms reached a negotiated agreement on 29 April 2026 to release every dog and wind down its breeding operation. 1,500 beagles are now being placed in homes by a coalition of established rescue organisations, with the costs of receiving and rehoming the dogs carried by the organisations on the receiving side — not by Ridglan. The model worked. It is portable. The American campaigners and welfare organisations who built it have made the playbook public and have offered direct support to UK groups working on the same problem. We believe a similar mutually beneficial commercial outcome is possible here.

Italy reached the same destination by a different route. The beagle-breeding facility at Green Hill, Brescia, was closed in 2012 by court-ordered seizure after a coalition of mainstream welfare organisations built a case the courts could not ignore. We mention this only as historical precedent in the public domain, without implying any parallel or suggesting legal risk to you. Simply to emphasise, we seek a voluntary commercial resolution instead of any litigation.

The international picture is also worth noting. MBR Acres Ltd is, on the public record, a UK subsidiary of Marshall BioResourcesin New York. The same group operates a sister facility, MBR New York, currently the subject of a US campaign by Save the Dogs USA. The pressure on the laboratory-beagle supply chain is not a UK-only story, and the wind-downs of the past year are not isolated events. We are writing to MBR Acres here in the UK because this is where we are, and because we genuinely believe a calm, negotiated resolution is achievable and in everyone’s interest.

We are writing in public, not in private, because the public has every right to be present in this conversation. We have written to MBR before. We have written to your customers. We have written to your regulator. We are writing this letter in public because none of the previous letters were answered, and we are no longer prepared to keep that pattern going. We are also open to a meeting at a location of your choice, with your legal representation present. We would prefer to begin discussions privately via solicitors on a without prejudice basis.

Independently of this proposal, lawful public advocacy on this issue — vigil, documentation, petitioning, parliamentary engagement and peaceful protest — will continue, as it has since 2021, for as long as members of the public choose to engage in it. That is the exercise of ordinary democratic rights. It is not contingent on your response to this letter, and it is not something this campaign offers to start, stop, or trade. Facility-specific campaigning from our group would cease upon successful completion of a transfer agreement.

We would be grateful for a written response within four weeksof receipt of this letter, which we appreciate allows time to take legal advice. If that is not enough time, we are glad to extend it by agreement. If we receive no response, we will take it that the company does not wish to discuss the matter at this time, and we will say so publicly and honestly — no more than that.

Yours, in the public interest,
