British Prime Minister David Cameron threatened to walk away today from a "make or break" EU summit without a deal as his counterparts warned they would not pay any price to stop Britain crashing out of the bloc.
"I'll be battling for Britain. If we can get a good deal I'll take that deal but I will not take a deal that doesn't meet what we need," Cameron told reporters as he arrived for the meeting in Brussels.
Cameron wants a deal on reforms to the 28-nation European Union before holding a referendum as early as June but many member states are hostile to Britain getting special treatment when they have grievances of their own.
Talks were going down to the wire on Cameron's four challenging demands -- welfare restrictions to help curb immigration, safeguards for non-euro Britain, increasing EU competitiveness and an opt-out from closer EU integration.
French President Francois Hollande said agreement with Britain was "possible" and that was what he wanted -- but raised fresh doubts over the protections for non eurozone countries.
"No country can have the right to veto, we cannot hold Europe back from advancing," he said. "It is the EU that is stake, not just a country."
Cameron won crucial backing yesterday from German Chancellor Angela Merkel who said Berlin had shared his concerns "for many years".
Arriving for the summit, Merkel said there were still some issues to resolve but she was "happy to do everything to create the conditions for Britain to remain part of the European Union", she said.
"This is important from a German point of view but of course this will be decided by British voters in the end."
For her part, straight-talking Lithuanian President Dalia Grybauskaite punctured some of the summit rhetoric.
"I think everyone will have their own little drama and then we will agree," Grybauskaite said.
European Commission chief Jean-Claude Juncker said he was "quite confident" of a deal, but former Polish premier Tusk was more cautious.
"We are in the middle of still very difficult and sensitive negotiations on the UK question. One thing is clear to me though: this is a make or break summit," Tusk told reporters.
