It's 'Brexit'. The very word conjures something quite painful. It's the idea the British people may vote to the European Union, and be the first country to do . The British government, with the Prime Minister David Cameron at the helm, renegotiating its relationship with Europe. A deal of sorts that would return sovereignty London. It would also the right of migrants to claim benefits the UK. But it's controversial. Other EU countries also want something this deal. Everybody says they want Britain to stay , but the British people not at all sure they want to be part of the EU . Oh, there are strong commercial reasons staying in Europe, but the Brits all the social bit that goes with the deal. So in the 18 months the British people get a chance to vote on the referendum. If they vote to leave, Brexit becomes a reality and things very messy.
