§ 33. Jeremy Corbyn
To ask the Secretary of State for the Home Department what his latest estimate is of the number of persons detained under immigration powers over the past 12 months. 
§ Beverley Hughes
The latest available information on the number of persons detained under Immigration Act powers relates to 30 March 2002. As at that date, 1,575 persons (to the nearest five) were being detained solely under Immigration Act powers.
I regret that statistics showing the total number of persons detained in the last 12 months could be obtained only at disproportionate cost by examination of individual case records, and no estimate of the total number has been made.
Information on Immigration Act detainees as at 29 June will be published on 30 August on the Home Office Research Development and Statistics Directorate website at http://www.homeoffice.gov.uk/rds/immigrationl.html.
