That's a very difficult question to answer in that it often is apples and oranges because the criteria for different countries is used in such different ways. What we would really need to look at is the outcomes of immigrants in the various countries to be able to really establish what's more effective in certain countries than in others.
However, we work closely with our five-nation colleagues to monitor what's going on to ensure that we're on the same wavelength. We recognize that we're in a friendly competition with them, as well. I don't think it's possible, though, to answer who is coming out on top.
