Nick Clegg has given a very interesting interview to the political magazine The House, here in Westminster.
The Deputy Prime Minister appears to admit that David Cameron's call for an in-out referendum will not be a deal-breaker for negotiations at the next election. He says:
That will come as some surprise to those in his party who are appalled at Mr Cameron's offer of a referendum.
But before anyone thinks Mr Clegg has gone soft, he reiterates his criticism of the Prime Minister's Europe speech given yesterday.
Mr Clegg calls it a "tactical victory today for a strategic mistake tomorrow".
