Nick Clegg has not ruled out a coalition with Labour after the 2015 general election but refused to be drawn into a debate on Ed Miliband's leadership.
Speaking to the BBC, the Deputy Prime Minister explained:
If the British people say that the most legitimate outcome of the next general election would be a Labour/Liberal Democrat coalition, of course I would be prepared to play my part in that.
However, he politely opted out of giving his thoughts on what Mr Miliband would be like as a Prime Minister:
I don't know, it hasn't happened yet. I don't think you should judge people until they've been able to prove themselves.
Mr Clegg denied that he was assuming he had the right to stay Deputy Prime Minister "forever and a day", but rejected suggestions that his removal as leader might be a price the Lib Dems would have to pay to go into coalition with Labour.
Nick Clegg believes that his party's place is in government and coalitions should be a permanent fixture in British politics.
Nick Clegg is a good speaker - possibly the best of the current crop - but I am not sure his conference address was his finest hour.
A majority of British voters prefer a single party government, according to a ComRes poll carried out for ITV News.
