Information on the number of foreign national prisoners serving an immediate custodial sentence in prison establishments in England and Wales is given in table 8.28 of the web tables of Offender Management Caseload Statistics 2004, available at the following address. http://www.homeoffice.gov.uk/rds/omcs.html These figures have been drawn from administrative IT systems. Although care is taken when processing and analysing the returns, the detail collected is subject to the inaccuracies inherent in any large scale recording system, and so is not necessarily accurate to the last whole number.
