Britain will release more than 2,500 prisoner early by the end of the year, with about 700 due out on 1 October. From January 2027, foreign offenders can be deported without first serving a minimum part of their sentence in a British prison.
For prisoners from Poland, Romania and Albania, the change moves the question from cell block to border control. Foreigners make up about 12 percent of the prison population in the United Kingdom, so the policy reaches far beyond a narrow group.
Mark Day and the receiving country
Mark Day of Prison Reform Trust said it is up to the receiving country to decide whether a deported prisoner serves the rest of the sentence: “to do kraju przyjmującego należy decyzja, czy deportowany ma odbyć resztę kary”. That means a deportation from Londyn does not automatically settle what happens after arrival in Warszawa or Bukareszt.
Mark Day also warned that “Jeżeli jednak lokalne służby nie otrzymają w porę kompletnej dokumentacji i wyroków, skazany może w ogóle nie trafić za kraty.” In practice, the transfer depends on case papers reaching local services before the person lands, because custody after arrival turns on paperwork as much as on the flight itself.
Londyn, Warszawa and Bukareszt
European capitals fear a case in which a convicted offender boards a plane in Londyn, lands in Warszawa or Bukareszt, and leaves the airport as a free person without any check. The British government says the program does not include terrorists or people convicted of the most serious crimes, but that reassurance does not remove the need for complete files on each deported person.
The scale is easier to see through the numbers. More than 2,500 prisoners will leave British prisons early by the end of the year, and about 700 are due to go on 1 October. That leaves a short window for any receiving state to decide whether to open a new case, continue a sentence, or let a deported person move on.
Mark Day called the situation “to tykająca bomba” and said, “Jeśli któryś z tych ludzi po wylądowaniu w kraju członkowskim zrobi coś potwornego, wybuchnie gigantyczny kryzys dyplomatyczny”. For Polish and Romanian authorities, the practical test is simple: whether the judgment and documentation arrive in time for custody to follow the plane.
January 2027 rule change
From January 2027, the new rules will remove the minimum-sentence requirement before forced deportation of foreigners. That makes the first check a document check, not a prison check, and puts the burden on the handover between the British authorities and the receiving state.
For anyone due to be released early this year, the immediate milestone is 1 October. For the larger policy shift, the open question is how British authorities will ensure that receiving countries get complete documentation before deported prisoners arrive.
