As many of you know, I am a complete idiot, so I need someone to explain this story to me.
'David Cameron has been accused of "blackmail" after he warned that Britain could leave the EU if a federalist becomes the next president of its executive arm' this is in relation to the appointment of Jean-Claude Juncker as EU President.
Now, for us to actually leave the EU, we'd have to have a referendum and there is every chance we could vote to stay in. So how can Cameron threaten to leave?
