asked the Secretary of State for the Home Department how many instances have occurred during the last two years of persons seeking temporary entry into the United Kingdom being detained in custody on arrival, notwithstanding the fact that such persons possessed appropriate entry documents that were ostensibly correct but which were treated as suspect by immigration officers; and in how many cases the persons detained were non-patrials.

A person who proved he was patrial under the Immigration Act would not be detained by the Immigration Service on arrival. The other information requested is not readily available and could be obtained only at disproportionate cost.
