The UK would coordinate such an important position with America. I wish that the UK could step out of America's shadow once in a while, but I am not holding my breath. Israel dictates American policy on Israel and the Palestinians. Through America Israel can effect several other nations like the UK. The rest of Europe is not so much influenced by either America or Israel. You can bet that Canada will also side with Israel, but unlike the UK, America has nothing to do with Canada's position. They are Israel groupies independently of America but for the same reasons. That's about how it will end. America, Canada, and the UK opposing a Palestinian state. The rest of the world in support.
