Key Takeaways
- Prison overcrowding in England and Wales is driving parties to explore overseas solutions.

- The Conservative Party proposes renting prison cells abroad, mirroring Norway‑ and Belgium‑run schemes in the Netherlands.
- Lithuania has explicitly rejected any talks of accepting UK inmates; Estonia is already paid per prisoner by Sweden under a detailed financial arrangement.
- Kosovo is open to further cooperation but says it must first fulfil its £170 million cell‑lease with Denmark.
- The Sweden‑Estonia deal shows how cost structures work: a base fee for a set number of inmates plus a per‑person charge beyond that threshold.
- Public‑sector imprisonment in England and Wales costs roughly £60 k per prisoner per year; overseas rentals can be cheaper or more expensive depending on terms.

Background on Prison Overcrowding and Political Responses
England and Wales continue to face severe prison overcrowding, with inmate numbers regularly exceeding official capacity. This pressure has prompted politicians from across the spectrum to look beyond domestic infrastructure for relief. While some advocate building new facilities or reforming sentencing, others see opportunity in using existing prison capacity abroad. The debate has intensified as parties seek short‑term fixes that can be implemented without lengthy construction projects or major legislative overhauls.
Reform UK’s Proposal to Transfer Foreign Criminals Abroad
At a Monday news conference, Reform UK leader Nigel Farage unveiled a plan to send foreign‑national prisoners to serve their sentences overseas, arguing that this could free up roughly 10,000 prison places in the UK. Farage cited El Salvador and Kosovo as primary destinations, and added that Baltic states such as Lithuania and Estonia could also be considered. A party spokesman clarified that the policy focuses on El Salvador, Kosovo, and “possibly others if they are open to the idea,” emphasizing that the goal is to alleviate domestic pressure while respecting international legal frameworks.
Conservative Plan to Rent Prison Cells Overseas
The Conservative Party has revived a previously shelved idea of renting prison cells in other countries, a policy they first introduced while in government in 2023. The model draws on arrangements already in place where Norway and Belgium rent cells from Dutch prisons to manage their own overcrowding. Conservative shadow home secretary Chris Philp described the approach as “an idea that we legislated for in government but Labour subsequently did not pursue,” framing the Labour government’s inaction as a “catastrophic mistake” that needs urgent reversal.
Political Criticism of Labour’s Inaction
Philp’s remarks highlight a partisan split over the viability of overseas prison solutions. He accused the Labour administration of abandoning a workable policy that could have eased pressure on the UK prison system. By labelling the omission a “catastrophic mistake,” Philp sought to position the Conservatives as the party ready to act decisively, while suggesting that Labour’s reluctance has exacerbated the overcrowding crisis.
Baltic States’ Reactions: Lithuania and Estonia
Lithuania’s Ministry of Justice responded firmly, stating that “there have been no discussions or consultations regarding the possibility of accepting the transfer of all Lithuanian citizens imprisoned in the United Kingdom” and that the government “does not see any scope for entering into practical arrangements of this kind.” In contrast, Estonia has entered into a financial agreement with Sweden: Sweden will pay up to £52 million (≈ €61 million) annually if Estonia houses 600 Swedish offenders at its Tartu prison, with an additional £7,254 (≈ €8,500) per prisoner per month for each inmate beyond the 301st. This shows a willingness to engage, albeit on a paid‑per‑inmate basis rather than a blanket transfer of UK prisoners.
Kosovo’s Stance on Further Prisoner‑Transfer Deals
Kosovo, which has already agreed to lease 300 of its jail cells to Denmark in a deal worth £170 million (≈ €200 million), signalled openness to further cooperation but stressed prioritising its existing arrangement. A Kosovo government spokesperson noted that the country “values the willingness of partner countries to initiate and advance new co‑operation initiatives that serve common interests, mutual priorities, and the strengthening of international justice mechanisms,” yet added that Kosovo would “focus on enacting its deal with Denmark before entering into any new agreement of a similar nature.” This caution reflects a desire to avoid over‑extending its prison‑leasing capacity.
Financial Mechanics of the Sweden‑Estonia Agreement
The Sweden‑Estonia contract illustrates how overseas prison rentals can be structured financially. Sweden pays a fixed annual sum for the first 600 inmates housed in Estonia’s Tartu prison, after which a per‑prisoner monthly charge applies. This model allows the host country to generate predictable revenue while the sending country gains certainty about placement costs. When compared to the UK’s public‑sector average cost of approximately £60,018 per prisoner per year (2024/25), the Estonian arrangement could be competitive, especially if the per‑inmate fee remains below that threshold. However, any additional administrative or logistical expenses would need to be factored into the overall cost‑benefit analysis.
Cost Comparisons and Expert Warnings on Overseas Prison Rental
Beyond the headline figures, experts and former ministers from both major parties have cautioned that renting prison space abroad may not automatically yield savings. The BBC has been told that previous assessments judged such schemes to be expensive, citing hidden costs such as transport, legal oversight, and potential diplomatic friction. While the per‑prisoner fee in the Sweden‑Estonia deal appears lower than the UK average, scaling up to thousands of inmates could erode those advantages. Consequently, policymakers are urged to conduct thorough feasibility studies, factoring in both direct expenditures and indirect risks, before committing to large‑scale transfers or rentals.
Overall Assessment and Outlook
The current debate reveals a shared recognition that domestic prison capacity alone cannot satisfy the demand created by rising inmate numbers. Reform UK’s focus on transferring foreign nationals offers a straightforward numerical gain—up to 10,000 places—but hinges on the willingness of third‑party states to accept UK prisoners, a proposition met with mixed responses. The Conservative approach of renting cells seeks to leverage existing international arrangements, yet faces diplomatic hurdles, as evidenced by Lithuania’s outright rejection and Kosovo’s conditional openness. Financial examples like the Sweden‑Estonia deal demonstrate that cost‑effective models are possible, but they also reveal the complexity of structuring such agreements to ensure value for money. Moving forward, any viable solution will need to balance humanitarian considerations, legal compliance, fiscal responsibility, and the geopolitical readiness of partner states to participate in prison‑transfer or rental schemes. Only through careful negotiation and rigorous cost analysis can the UK hope to ease its prison overcrowding without creating new burdens elsewhere.
