Migrant Domestic Workers (Visas)

I will come to that. The hon. Gentleman said that he was trying to tie down the present and future Governments, but it is sensible that the current Minister—and any future Minister, whether that is me or someone else—should proceed on the basis of hard evidence. Different solutions may be necessary, depending on the scale of the problem. It has struck me during the debate that people are saying that there is a solution. I suspect that there are two or three solutions. We all want to clear the problem up, and any sensible Government that want to eradicate it may have to take several different steps, which will have to be based on evidence of the scale of the problem. The hon. Gentleman is saying that one instance is one too many, and that the Government must do something about the problem. That is true, but he has been in the House long enough to know that such reasoning is often not the basis for the best and most effective policy making. I want to ensure that we eradicate abuse, and to do so effectively we need better evidence than we have at the moment. That is why I hope that the Minister can produce that evidence.
