asked the Secretary of State for the Home Department how many people were detained overnight during 1986 in (a) Harmondsworth detention centre, (b) Queen's building, Heathrow and (c) Beehive, Gatwick.
[pursuant to his reply, 10 April 1987, c. 421]: The information requested is as follows:
asked the Secretary of State for the Home Department what was the total number of passengers detained overnight under Immigration Act powers during 1986, by nationality.
[pursuant to his reply, 10 April 1987, c. 421]: The available information relates to passengers held in Immigration detention units and police cells. No central record is maintained of the nationality of passengers detained in Prison Department accommodation and this information could only be obtained at disproportionate cost. As some passengers were detained in more than one location, there is an element of double counting.
