To ask the Secretary of State for the Home Department how many illegal workers whose employment has been the subject of penalties pursuant to section 15 of the Immigration, Asylum and Nationality Act 2006 (a) have been deported and (b) are still in the UK.

We are better placed than ever to identify and charge those working illegally.

We are increasing our multi agency taskforces, improving our intelligence sharing between Departments and creating a strategic intelligence picture and structure. Through the Immigration Bill, we are simplifying the existing illegal working penalty regime making it easier to enforce payment in the civil courts.

It would not be possible to provide the information requested without linking immigration case outcomes to our data on civil penalties issued on employers. This would incur disproportionate costs.
