Former Belgian PM: UK's EU re-negotiation 'impossible'

A re-negotiation of the UK's position in the European Union would be "impossible", the former prime minister of Belgium has said.

Guy Verhofstadt, who is a sitting MEP, told the BBC's Newsnight that such discussions by individual member states "would be the end of the European Union".

Mr Verhofstadt said that all member countries would be part of a "collective re-negotiation" following European elections in 2014.
