The section of the National Audit Office report on Asylum and Migration statistics published on 25 May 2004 to which is referred relates to the accuracy of statistics held by IND (now known as the UK Border Agency) governing the number of individuals held in detention for immigration reasons.
Since the report was published, the DELMIS system, to which it referred, has been superseded by a different system known as the Case Information Database (CID). This is designed for use within all areas of the agency as opposed to just the Detention Service Directorate. It is through CID that the agency is able to ensure that it keeps accurate records on all individuals’ immigration cases as well as ensuring that caseworkers are aware of where an individual resided or whether they were detained.
The chief executive of the UK Border Agency has written to the Home Affairs Committee on several occasions over the past 18 months and explained that we have reviewed and strengthened our processes in identifying those foreign nationals serving custodial sentences and should be considered for deportation following the events of April 2006.
