I entirely accept what the noble Lord says; it may well be the tip of an iceberg. However, I am setting out that the Government are trying to tackle this problem, in a way that previous Governments have, by the dual action of contacting the employers and the workers to ensure that both are aware, before they come to work in this country, of their rights and responsibilities.
I entirely accept the difficulty of identifying the people who are abused, but I assure noble Lords that anyone who is abused, once that comes to light, will be treated with the sort of help and support that one would expect from a country with our rich tradition of giving refuge to people who have problems. While working over here, they of course have the protection of UK employment law. Anyone who believes that they are being mistreated can take action to report it. As I say, the measures we are taking extend the ones that previous Government have taken. The numbers that are coming forward appear to be stabilising because we are taking measures to try to ensure that the employers and the workers have a full view of their rights when they come here.
