My hon. Friend is making a very important point. A matter that attracted quite a bit of controversy about 10 years ago was the number of people coming to this country as refugees or asylum seekers, from sub-Saharan Africa in particular, suffering from TB. The question to NHS England at that point was, should they be screened on entry? There was sensitivity about whether that was discriminatory and whether it was the right thing to do. It now appears that there has been an adjustment to the attitude of NHS England, which is screening people much more effectively. We need to let people know that they are carrying the disease and we can help them, but that means that we need to check them as they come into the country. There is great sensitivity about that, and I am not sure what the current position is.
