§ Mr. Alex Carlile
To ask the Secretary of State for the Home Department if he will estimate how many illegal immigrants are working in the London area; and if he will make a statement.
§ Mr. Charles Wardle
Comprehensive information on the number of persons working in breach of the conditions imposed on their leave to enter or to remain in the United Kingdom is not available. In many cases it is not possible to determine whether a person is working illegally until he/she has been traced and interviewed.
