Our colleague Jo is back in the corridor outside the room in the Commons where Tory MPs will begin voting in 20 minutes.

She says the executive officers of the 1922 Committee have arrived and preparations are under way to open the ballot boxes.

Here's more on that story about Labour MPs in Leave areas who are calling for Jeremy Corbyn not to fully embrace another Brexit referendum.

Their letter says their party was "devastated" in the local elections and the strength of The Brexit Party in Labour heartlands proved more of a "potent threat" than other parties.

A commitment to a further referendum would be "toxic to our bedrock Labour voters", the letter says, and it would "jeopardise our role as a party of the whole nation".

A bit more from Ian Lavery, Labour Party chairman, on that apparently rogue tweet we mentioned earlier.

He's posted another message saying Twitter have confirmed there was unauthorised access to his account from someone outside his team.

Former leadership contender Dominic Raab says Boris Johnson’s comments last night on leaving the EU before 31 October have been “over-interpreted”.

The frontrunner was asked to give an explicit guarantee of leaving by this date come what may, but replied simply that leaving before that date was “eminently feasible”.

But Mr Raab, who is now backing Mr Johnson, tells the BBC he is “100% committed to this”, and he has received a personal pledge from him to that effect.

“He is the candidate to get us out by the end of October”, he adds.

Ian Blackford says the Tory leadership front runner is "racist" and is "stoking division in communities". Read more.

Ian Lavery, the chair of the Labour Party, has disassociated himself from a message posted on his Twitter account claiming his party wanted to stop Brexit by revoking Article 50.

The message, sent earlier on Wednesday to Sky News journalist Sam Coates, came as Labour's shadow cabinet met to discuss the party's position on another referendum.

Mr Lavery said the message had not "been authorised by him or his team" and "appropriate security updates" had been taken.

The Wansbeck MP is one of most vocal opponents of another Brexit referendum - saying it would be a betrayal of the 17.4 million people who voted to leave in 2016.

Interesting story from the Huffington Post this lunch time. They've spoken to sources with a hotline to the Democratic Unionist Party - the DUP, you'll remember, has propped up the Conservative government since it lost its majority at the 2017 general election.

Rory Stewart, one of the leadership hopefuls, says his Brexit strategy is to find a way to get Theresa May's thrice-rejected deal through the Commons. It sounds like the DUP would not be happy if that happened...

MP Anne Marie Morris was backing Dominic Raab until his elimination on Tuesday.

She's switching her support to Boris Johnson but isn't totally sure how committed he is to the 31 October Brexit deadline.

"I think he's playing politics and by that I mean he's making the clear point that if you're in a negotiation if you aren't prepared to walk away you're not going to get very far.

"Secondly, he recognises he's got to appeal to a very broad range of individual MPs and the vast majority are Remainers. So he's trying to leave himself some wriggle room.

"But the mathematics are such that if we don't get out on 31 of October, frankly, the party is history."

A reminder of what's coming up this afternoon leadership contest-wise.

At 15:00 BST voting will begin in the third round of the race. Overseen by the backbench 1922 Committee, Conservative MPs will file in over the following two hours to pick one of the five remaining candidates.

The results will be counted and the result announced at about 18:00. The candidate with the fewest votes will be eliminated.

PMQs is now over, and Treasury Minister John Glen is making a statement on government plans to help people with high levels of personal debt.

The Treasury is to give them a two-month “breathing space” during which they will be protected from enforcement action from creditors.

During this period, those eligible for the scheme will also see their interest, fees and charges frozen. The scheme is due to begin in 2021.

Reality Check

We've been looking at a few more of the claims from last night's Conservative leadership debate to see whether they really stack up.

Let's start with this one from Sajid Javid.

Dominic Raab's decision to back Boris Johnson would suggest that Mr Johnson is on course for an even bigger win in tonight’s ballot.

Mr Raab said Mr Johnson was the man to make Britain feel good about itself again.

He also sought to dispel suggestions that Mr Johnson - as prime minister. - might not take the UK out of the EU by 31 October, after he failed to make such a commitment during last night's television debate.

Pressure, meanwhile, is mounting on his rivals to join forces in a bid to thwart Mr Johnson.

This morning Rory Stewart confirmed he was in talks with Michael Gove - although the prospect of a pact would appear remote given both men want the other to drop out.

Mr Stewart has acknowledged he put in a lacklustre performance last night and it seems he now faces a tussle with Sajid Javid to avoid being eliminated.

Tooting MP Rosena Allin-Khan asks about policing numbers in the wake of further deaths in London.

"This senseless violence could have been avoided with adequate policing," she says.

She asks if the PM will leave a legacy that will change the path of these young people?

Mrs May says no-one ever wants to see a young life taken.

"They are people who have had a future ahead of them," she says.

The government introduced a serious violence strategy and is working with police and other organisations to ensure young people are turned away from using violence, she says.

But it is a "wider issue" than police numbers, Mrs May insists.

She then suggests Ms Allin-Khan should talk to the Labour mayor of London about the issue.
