My hon. Friend is making a most powerful speech, and I agree with everything that he is saying. Does he agree that it is important to look at the means of retaining those bright graduates who come here and train? They are precisely the people who might wish to start their businesses in the UK. We need a scheme that makes it possible for them to remain in the UK, without having to leave and come back, so that they can move from graduate employment into the sector, using their skills. We would then get the brightest and best from day one.
