EU Treaty change calls widens split
David Cameron's difficulties with his party's eurosceptics deepened as France and Germany renewed calls for EU Treaty change to solve the single currency crisis.
After emergency talks in Paris, French president Nicolas Sarkozy and German chancellor Angela Merkel said they wanted change to be carried out by all 27 member states if possible - or at least the 17 eurozone countries.
The aim would be to allow far tougher rules and sanctions governing the eurozone in future to reassure markets about the euro's long-term stability.
Downing Street insisted that the scale of the proposal - to be put to an EU summit later this week - did not amount to change warranting a referendum in the UK.
Deputy Prime minister Nick Clegg said as much on Sunday, insisting a referendum was only needed if Treaty change meant giving up more UK sovereignty to Brussels.
But Work and Pensions Secretary Iain Duncan Smith sided with the eurosceptic right in the Tory Party by suggesting that the impact from any Treaty change would demand a national vote.
"The Prime Minister has always been clear, if there are substantial changes that affect Britain's position, then he would go for a referendum because that's what we said to the British public we would do" said Mr Duncan Smith.
As Tory eurosceptics stepped up their referendum calls, Mr Cameron insisted nothing had changed to justify such a move.
Answering questions following a speech in London, the Prime Minister said: "Clearly, there are negotiations going on in Europe. I will be part of those negotiations on Thursday and Friday. If there is a Treaty at the level of 27, and if that passed powers from Britain to Brussels, there would be a referendum."
But he made clear he does not expect any Treaty change which would be significant enough to require a referendum, adding: "We have legislated now so that it is impossible for a British government to pass power from Britain to Brussels without asking the British people in a referendum first.
