Campaigners against Scottish independence have been accused of "blatantly misrepresenting" comments made by the new European Commission president on European expansion.

Prime Minister David Cameron had claimed Jean-Claude Juncker's remarks stating there would be no new members of the European Union in the next five years were "very important" in the run-up to the Scottish independence referendum.

While the political guidelines issued by Mr Juncker do not refer specifically to Scotland, he said the EU needs "to take a break from enlargement" to consolidate its achievements.

He added: "This is why, under my presidency of the Commission, ongoing negotiations will continue, and notably the Western Balkans will need to keep a European perspective, but no further enlargement will take place over the next five years."

Deputy First Minister Nicola Sturgeon said the new EC president's spokesman had made clear the comments did not refer to Scotland.

She said "despite that ­clarification", the pro-UK Better Together campaign "continues to carry bogus claims and false assertions, blatantly misrepresenting Mr Juncker".

Mr Cameron told MPs at Prime Minister's Questions yesterday he "whole­heartedly" agreed with Mr Juncker's remarks.

He said: "It is noticeable what he said, that there wouldn't be new members joining the European Union in the next five years, and I think that is very important in the context of the Scottish referendum debate."

SNP Westminster leader Angus Robertson later called on the Prime Minister to "correct the record" in the House of Commons, "withdraw the bogus assertions and apologise to the chamber".

Ms Sturgeon wrote to former chancellor Alistair Darling, the leader of the Better Together campaign, calling on him to "withdraw the No campaign's false claims about Scotland's future in Europe".

A spokesman for Better Together said: "President Juncker's comments lay bare the full extent of the problems we would face if we left the UK. The countries who have already started the application process to join the EU face a five-year wait.

"As President Juncker has made perfectly clear previously, if we leave the UK, we would then have to start the application process to join."
