Why have the Government betrayed these people?

Because the British government is, unfortunately, a shambles. I'm sure when they promise these things they mean it but they tie themselves in knots and then everything fails. Also they are too preoccupied with ensuring that immigrants are able to live of our tax system without working that they forget the important things. Get rid of Gordon Brown asap as he is even worse (and I never thought that would be possible) than Tony Blair. Our government needs to take a long hard look at the Australian government and take some tips of them! x
