I do quite like Nick Clegg, but I have to say David Cameron has looked the most assured by a margin tonight. His best performance yet.

Mr Clegg ridicules the Conservatives for their position on Europe, suggesting that they seem to change their minds fairly regularly. He says: "I don't know what they're going to think on Europe next Tuesday." Mr Clegg adds that there should be a referendum on the EU - but only when there are plans to give over new powers to Brussels.

Challenged on freedom of movement within the EU, Mr Clegg says a problem emerged when it became "freedom to claim". The coalition government had changed the law to deal with that. It shouldn't be forgotten, he said, that as many British people were living and working in the EU, as EU people were working in the UK.

There's an impassioned moment for Nick Clegg when he defends his decision to go into coalition with the Conservatives. He declares: "I will never apologise....for having stepped up to the plate in a plucky and brave way."

A member of the audience wonders whether on 8 May, the first person he speaks to will be the party leader with the most seats. Mr Clegg says the party with the most seats has the right to make "the first move".

The Lib Dem leader says that if either David Cameron or Ed Miliband think they are going to win a majority "they need to go and lie down in the darkened room". (See earlier entries about coalition talks.) Touche.

One member of the audience asks if the Lib Dem leader has plans for a new job if things don't go his way after the election, and his party ends up an "irrelevance". Nick Clegg has a short answer: "No I don't."

Mr Clegg says the Conservatives and Labour Party would both cut the amount of money going into schools, colleges and nurses. He declares that the Lib Dems would not go into any coalition with a party planning to reduce education spending, what he calls "shortchanging the little children of today".

Mr Clegg says the next government has to deal with the national debt but has to do so fairly. The Conservative plan, he says, balances the books but unfairly. Labour, he asserts, is offering no timetable or detail on how it plans to deal with the debt.

Reality Check

Nick Clegg says the £12bn of welfare cuts that the Conservatives are planning is the "equivalent of £1,500 off eight million of the most vulnerable families". We're not arguing with his sums, but not sure where the eight million households figure comes from.

Bethany Cowling asks Nick Clegg about "leaking details" the Lib Dems were privy to as part of a coalition. He retorts that they were "hardly leaked". He says that unless the Conservatives "come clean" on welfare cuts "we can only assume" they're looking at the plans they floated in government. He argues the Conservatives must say who they're going to hurt.

Mr Clegg defends the current system of university tuition fees. It is, he says, "much, much fairer" than the system left by the last government.

Eagle-eyed viewers might have spotted Ed Miliband narrowly avoiding a tumble as he left the stage.

It's now Nick Clegg's turn. First up is a question on breaking his promises on tuition fees. Mr Clegg jokes: "A nice easy way to start!" He continues by saying that in life you can't do everything you want and he asks that people at least give him credit for what he has done.
