It was perhaps a sign of the scale of Labour's defeat that the candidates for the party leadership were asked all about a politician who wasn't here - the SNP's Nicola Sturgeon - and what qualities they shared with her that could make them more successful.

This didn't engender a bout of soul searching about Labour's meltdown in Scotland - instead the candidates swiftly and unsurprisingly turned the question to their advantage.

Yvette Cooper said it was time for Labour to break the glass ceiling and elect a woman leader - unsurprisingly Liz Kendall agreed. Middle England The two women each had different pitches, though - the former had run a big government department, she said, while the latter described herself as "a fresh start".

Andy Burnham saw the SNP's success as evidence that people were fed up with a political elite and he was the man to take his party out of the Westminster bubble.

The most left wing of the candidates - Jeremy Corbyn - preferred the nationalists' anti-austerity message.

We've heard a lot from the Labour party about how there needs to be a full and frank debate about why the party lost. That every voice must be heard. That's why Jeremy Corbyn got on the ballot.

If that is what the party wants and needs tonight was something of a lost opportunity. Because it wasn't really a debate, it was almost like a series of one on one interviews with the audience.

Andy Burnham's assertion that "the party comes first, always" is the focus of plenty of pundits. Liz Kendall swiftly interjected to say "the country comes first". For Spectator editor Fraser Nelson, external, Ms Kendall "won a one-hour debate with just four words". Philip Collins, of the Times, says:

The most striking element of the Newsnight Labour leadership debate came in the candidates' answers to our own Laura Kuenssberg, who ended the quizzing with a simple question: would you be willling to resign before the next general election if it looks like Labour are not going to win with you as leader?

The answers, in order, ran:

• Liz Kendall: Yes. because more than anything, I want Labour to win so we can change the country... There are some MPs who are talking about having a new process whereby if colleagues think you're not doing well enough, you can go. I have to go through that as a local Labour MP. We should have that for the Labour leadership, too..." 
• Jeremy Corbyn: "I think there should be an opportunity to elect or not elect the Labour leader every one or two years..." 
• Andy Burnham: "Of course, there should. Yes is the answer to your question... The party already has that rule, . The debate maybe is: 'do you make that easier.' The party comes first, always."
• Yvette Cooper: "The party already has rules to do that kind of thing... [After the leadership election] our focus has to be holding the Tories to account." Pressed by Laura about a rule change, she stuck to her guns: "It's up to the Labour party to choose and not for us."

Supporter Andrew Fisher said Jeremy Corbyn's views "had resonated very well in the hall tonight". He came across with a clear vision and people responded to it, said Mr Fisher. He rejects the idea that Labour's election manifesto had failed to inspire because it was too left wing - people want a bold vision that is practical, he says. 

Chris Bryant says Yvette Cooper had taken the battle to Theresa May for five years so people know she is "competent" and "clever", But you saw a lot of the "real Yvette tonight":

Lord Falconer, from the Burnham camp, says that Andy "was direct, passionate and measured" and tried to make it clear that Labour have to get the positions the public care about - it's not about whether you're Blairite or Brownite or anything else.

Liz Kendall's campaign manager Toby Perkins (left in the pic above) says that "the line of the night that everyone's going to remember" was Andy Burnham saying you've got to put the party first and Liz Kendall saying you've got to put the country first.

BBC political correspondent Iain Watson says it was interesting that part of the debate was dominated by a politician who wasn't here - Nicola Sturgeon. He says the contest is all to play for given there's a completely new way of electing a leader. He says it is very difficult to predict how it will go.

That's your lot for the live debate. Friendly-looking chat between the four as the credits roll. In 85 days, one of them will be Labour leader. Now it's time to turn to the post-match analysis

Are you prepared to be replaced before the general election, if it looks like Labour won't win, asks Laura Kuenssberg. Yes, says Liz Kendall: "Because more than anything I want Labour to win so we can change the country". Jeremy Corbyn says the leader should be re-elected regularly anyway. Andy Burnham says "of course" Labour should be able to get rid of a failing leader. "I'm someone with my feet on the ground," he says. Yvette Cooper says Labour already has rules to allow a leader change.
