asked the Secretary of State for Employment what was the number of people granted entry to the United Kingdom in the years 1973, 1974 and 1975 to work in specific industries; and what check is kept to see that such people continue to work in the industry for which entry was granted.

Statistics of work permit holders arriving in Great Britain are kept by the Home Office but are not analysed by industry. The number of work permits issued by my Department in the years 1973, 1974 and 1975 to enable people to enter the country and take jobs in specific industries is as follows. My Department does not carry out specific checks on the work being done by work permit holders. However, if a work permit holder wishes to change his job he must first obtain the permission of my Department, and if he wishes to remain in employment beyond the period of 12 months for which permits are initially issued he must first apply to the Home Office.
