Sweden has begun moving prisoners to a prison in Estonia after a bilateral agreement was signed last year to lease part of the Tartu facility. The first four inmates arrived on a military aircraft at Amari airport on Tuesday and were escorted by police to the prison, marking the start of a programme that could see as many as 600 Swedish detainees housed abroad.

The arrangement, announced by Swedish Justice Minister Gunnar Strömmer, is intended to relieve a chronic overcrowding problem in Swedish prisons. Over the past decade the number of people behind bars in Sweden has more than doubled, reaching over 11,200 in 2024, driven by a rise in gang‑related violence and tougher sentencing. The Swedish Prison and Probation Service has described the situation as a "crisis".

Estonia, by contrast, has a surplus of cells, roughly two‑thirds of the capacity at the Tartu prison have been empty for years, and national occupancy sits at about 60 percent, the second‑lowest rate in the EU. With only around 1,600 inmates nationwide, the country sees the deal as an opportunity to make better use of its infrastructure and generate employment in the region.

Financial and operational details

Under the five‑year contract Sweden will initially transfer 300 prisoners, paying €30.6 million a year for the lease. If the number rises to the full 600, an additional €8,500 per inmate per month will be added to the bill. Swedish officials argue the deal saves money: keeping a prisoner in Sweden costs up to €11,500 per month, so the Estonian option is cheaper per head.

Estonian authorities have said the agreement will bolster the prison's infrastructure. Minister Jüri Pakosta described the partnership as historic and highlighted the potential for job creation in Tartu. The prison will operate under Estonian law, but Swedish officers will be present to train local staff and ensure the rights of the transferred inmates are respected. Prisoners will have access to basic amenities, a bed, chair, table, television, radio, alarm clock, wardrobe, mirror and window coverings, and staff are expected to communicate with them in English.By October, the plan is for 100 Swedish inmates to be housed in Tartu, rising to 200 by year‑end, with further transfers scheduled for 2025. The first group of four arrived on a plane that landed at Amari, an hour's drive from Tallinn, before being driven to the prison under police escort.

Reactions and concerns

The deal has attracted criticism in both countries. Swedish trade unions worry that outsourcing prison space could set a precedent for further cost‑cutting measures that shift public responsibilities onto private or foreign providers. They also question whether the welfare standards for inmates will be maintained in a foreign setting.

In Estonia, some civil‑society groups have raised concerns about the impact on local communities and whether the influx of foreign prisoners could strain resources despite the current vacancy. However, the Estonian Prison Service points out that the facility has been under‑used for years and that the partnership will bring additional funding and training opportunities.

Both governments maintain that the arrangement is mutually beneficial. Strömmer argues that the agreement "significantly relieves the burden on the Swedish prison system", while Pakosta says it will "strengthen Estonian prison infrastructure and create jobs".

The initiative reflects a broader European trend of cross‑border cooperation in justice and corrections, as some member states grapple with overcrowding while others face under‑utilised facilities. It also raises questions about the future of prison policy in the EU, where the balance between national sovereignty, cost efficiency and human rights standards remains a delicate one.
