EU leaders accuse Cameron of sabotaging budget deal Diplomats suggested that if the summit ends without deal, France will attempt to blame Mr Cameron and his stance on the rebate for the failure. Guy Verhofstadt, an MEP and former Belgian prime minster, also attacked Mr Cameron over his negotiating tactics. He said: "It's not necessary to isolate Cameron. He isolates himself. However, British sources insisted that many of Mr Cameron's arguments are supported by countries including Germany, the Netherlands and Sweden. Mr Cameron's role in the impasse was welcomed by Bill Cash, a leading Eurosceptic. If he comes back and says 'I'm standing firm on having a real cut, and not playing games with words here, he has done as much as anyone reasonably could. Richard Corbett MEP, an adviser to Mr van Rompuy, said: "Most people around the table want to make a deal." He said the sums under debate were 0.05 per cent of Britain's GDP. It's not very significant. This is a political challenge.
