The 'joke' he made about supporting anyone but England

Then he says he was angry with Salmond for waving the Scottish flag behind him when he won Wimbledon, he went on to say he had played for GB and not Scotland since he was a kid

Then he tweets his support for Scottish independence, saying he would probably be playing for Scotland.

You can see why some people might be off with him, it looks like he is 2-faced, changing his allegiance when it suits him
