That hour seemed to fly by. The questioners were brilliant, I thought. I know from experience that going on telly and being fluent isn't easy - let alone when you don't do it regularly and you're asking questions of very senior politicians on prime time. And it is even harder when you are not in the same room, you're staring into a funny looking camera and you can't see the people you are talking to. Bravo to them I say.

The debate has finished - phew!

Candidates face the next round of voting tomorrow, when at least one more candidate will be kicked out.

Coverage continues on the BBC News Channel and on Newsnight on BBC Two at 10:30 BST.

Stay tuned on the live page for more reaction.

Jeremy Hunt says there shouldn't be another election until Brexit has been delivered.

Rory Stewart says there shouldn't be one until the Tories have "regained trust".

Sajid Javid strikes a similar tone, saying the "most important thing" is that the Conservative Party unites to deliver Brexit before there is another election.

There isn't exactly enthusiasm for one any time soon from any of the wannabes. No surprise given how the Conservatives were tonked in the local and European Parliament elections.

The final question is from Aman in London, who asks the candidates when they would be prepared to call a general election - given the winner of this contest will get into Downing Street without one.

Reality Check

Asked who impressed her the most with their answers, Erin - who asked the question on climate change - says: "To be honest none of you have really impressed impressed me in the way that I'm looking for."

She says she doesn't think any of the candidates are willing to take "drastic, critical action".

Jeremy Hunt says the issue of climate change is a "fundamental matter of trust" between younger and older generations.

He says he is already committed to the current 2050 target - and on trying to do it faster, he won't commit but says it's right that the questioner has challenged them all to go further.

The race frontrunner says he still has "grave reservations" and "grave concerns." But will he rule out Heathrow expansion? He ducks answering that directly.

Mr Johnson answers the climate question in part by focusing on Heathrow. He says: "I continue to have grave reservations about Heathrow runway three."

Noise pollution and air pollution are his biggest worries, he adds.

More broadly, he tells the questioner he will put climate change "at the centre of my programme".

The next question is from Erin, aged 15, who asks the candidates whether they will commit the UK to achieving net zero carbon emissions by 2025.

(The current government target is to do this by 2050).

My colleague @alexforsythBBC points out that while Sajid Javid claims he increased council spending power as minister for local government, be aware that’s very different to grant funding which has steadily reduced since 2010.

Spending power has increased year on year since 2015/16... that takes into account councils’ ability to raise council tax and some councils who can keep hold of more business rates.

... sitting next to each other, Mr Javid asking questions directly of Mr Stewart. On the face of it, they are two most vulnerable to dropping out of the contest tomorrow...so the battle is intense.
