HC Deb 08 July 1986 vol 101 c102W
Mr. Dubs

asked the Secretary of State for the Home Department how many passengers detained at least overnight in each quarter since January 1985 were held (a) in prison department establishments and (b) in police cells.

Mr. Waddington

Statistics are not maintained in the form requested, and are recorded on an annual basis. In 1985 a total of 582 passengers were detained overnight in prison department establishments, police cells, or other accommodation not managed by the immigration service. The figure may include a small element of double counting in respect of persons transferred between different detention accommodation.
