asked the Secretary of State for the Home Department what is the official estimate of those gaining admission to the United Kingdom as visitors and failing to return home in the year 1975 to 1979 on an annual basis.

I regret that no such estimate is available.

asked the Secretary of State for the Home Department (1) how many visitors to the United Kingdom, having been granted temporary admission following representation from an hon. Member of this House, failed to return to their country of origin within the allowable time ;(2) how many representations were made by hon. Members of this House requesting temporary admission for visitors to the United Kingdom in the years 1975 to 1979, on an annual basis.

The information is not available, except at disproportionate cost.
