Judges are among those who have voiced outrage that Britain was unable to stop the offenders moving to Britain despite having been convicted of vile crimes in their own countries.
Criminals detailed in the dossier include Latvian Arnis Zalkalns who had been convicted of murdering his wife in 1998 before moving to Britain where he worked as a labourer.
Zalkalns, who was found hanged in October 2014, is believed by police to have murdered 14-year-old Alice Gross. Her body was found in September 2014 after she disappeared in August.
Victor Akulic had several convictions in his home country of Lithuania, including for raping a seven-year-old girl. After moving to the UK he beat and raped a woman in Kent in 2010 an horrific attack which he filmed.
In 2012 when he appealed against the terms of his jail sentence, Appeal Court Judge Lady Justice Hallett demanded: “Do we have to take in anybody, even if they have a conviction for raping a child?”
Akulic was not on a “watch list” of criminals and terror suspects which UK border staff check arrivals against. The Border Agency said it relied on overseas police to provide information but this had not happened in his case.
Failure to share the intelligence also leaves foreign offenders, once they have served sentences in their home countries, free to make new lives in the UK unhampered by the supervision imposed on British serious criminals after release.
