I don't think anyone thinks Britain is literally full, but there is a strain on things like the NHS and other public services that adding a new city's worth of population each year, before you count in refugees, won't help. Personally I think our approach to the refugee crisis has been the best one, and all countries should put more money into the camps outside Syria, as I suggested yesterday. There are still people vulnerable within those camps though, and we need to give them priority, and we can do proper checks on them. We can also control the numbers. The key is having control.
