Europe debate with Deputy Prime Minister Nick Clegg and Ukip leader Nigel Farage #europedebate
Live video coverage of the second debate
Nick Clegg is expected to ramp up his attack on Ukip leader Nigel Farage tonight when they face off in a second televised debate.
You can watch the entire debate LIVE - with comment and reaction on how each of the politicians performed.
Round two - 'Ding, ding'
Heading into Wednesday's debate, polls suggested the Deputy Prime Minister came off worst in the first clash last week, which included arguments over immigration figures and the number of laws coming out of Brussels.
But Mr Farage was criticised over recent days after naming Russian president Vladimir Putin as the world leader he admires most.
Mr Clegg has already branded the comments "grotesque" and "extreme", and is almost certain to raise them during the discussion.
Mr Farage has insisted he was merely expressing respect for Mr Putin's handling of the Syria crisis, not his political approach.
Ukip said its membership surged to over 35,000 in the LBC radio hosted debate last Wednesday, and party strategists will be hoping he can raise their profile further.
Meanwhile, Mr Clegg is seeking to gain wider advantage by painting himself as a conviction politician - and the only genuine pro-European among the main three leaders.
A poster launched by the party ahead of the showdown on BBC2 this evening mocks David Cameron and Ed Miliband as "missing in action", saying the Liberal Democrats are the only ones "standing up for British jobs".
Party president Tim Farron said: "David Cameron and Ed Miliband have ducked these debates. Nick Clegg is the only political leader prepared to put his neck on the line and stand up for British jobs.
The Liberal Democrats said their membership figures were also rising - with around 500 joining so far in 2014.
But its total of around 44,000 remains more than a third lower than the 65,000-plus levels it enjoyed before joining the Conservatives in coalition government in 2010.
A Liberal Democrat spokesman said: "This is great news and a further sign that the feel-good factor is well and truly back in the Liberal Democrats.
"As a party we are on the front foot, making the case confidently that only the Liberal Democrats can build a stronger economy and a fairer society, enabling everyone to get on in life."
Membership of the established parties has seen a steady decline for some years.
Conservative constituency numbers have almost halved since David Cameron became leader in 2005 - from 253,600 to just 134,000.
And while Labour's membership rose significantly when Ed Miliband became leader and remains above its 2009 level, it has steadily slipped back to stand at 187,537.
Mr Cameron's official spokesman said the Prime Minister would not be watching the debate live this evening.
"I expect, like last week, he will catch the highlights as part of the news bulletins tonight," said the spokesman.
Asked why the PM would not tune in to the debate, the spokesman said: "The Deputy Prime Minister wanted to debate the approach to the EU with Mr Farage. He is perfectly entitled to.
"The Prime Minister has set out his approach very clearly and he is interested in making the case for his own approach to the EU."
