My hon. Friend makes a powerful point, and that is why we take the approach that we do. We want to ensure that when we have an enhanced preferential trade relationship with a country, visas can go into the mix. That is the global practice right around the world. But it is crucial, as a matter of sound policy but also for retaining public trust in our migration system, that we have control over things people care about: the numbers of people coming here; ensuring the people coming here are self-sufficient; and making sure that if people threaten this country or commit criminal offences, they can be removed.
