According to Zoe Williams, Britain's disastrous nul points showing in the Eurovision Song Contest is a warning shot. Now we in Britain can see, if we can bear to look, just how all of Europe thinks of us. And we have only ourselves to blame, with our superior attitudes and stand-offish ways.

"If we take any political message at all from this disaster, it is referendum, and referendum now - if we feel this shame keenly, imagine what it would be like if we didn't get a chance to reject the superstate, before the superstate rejects us."
