My hon. Friend is right. We must tackle the illegal working and also the exploitation that can often drive a lot of what happens. That is why we are intensifying the immigration enforcement, which is part of our new, huge expansion to the returns and enforcements unit. He is right that the process, which has become too complicated and too bureaucratic, needs to be simplified to make sure that the rules are being enforced. We have set out the high-risk sectors on which we wish to focus this summer, but we need a more systematic approach. We have talked about a single enforcement approach, and we will be setting out more details about those plans.
