Foreign national prisoners who will be subject to deportation at the end of their sentence are not eligible for release under the End of Custody Licence scheme. I refer the hon. Member to the regular publication 'End of Custody Licence: releases and recalls', copies of which are available from the Library of the House and the Ministry of Justice website
Between 29 June 2007 and 31 March 2008, there were 23,716 releases from all prisons in England and Wales under the End of Custody Licence Scheme. Of these, 1,384 were foreign national prisoners (6 per cent.) not liable for deportation, consisting of 767 EU nationals and 617 non EU nationals.
These figures have been drawn from administrative IT systems, which, as with any large scale recording system, are subject to possible errors with data entry and processing.
