Leadership frontrunner Boris Johnson - who has topped all three previous polls - made no comment to waiting journalists this morning.

His critics say he is avoiding media spotlight and thus scrutiny of his policies.

But his supporters argue that he has been scrutinised in private Parliamentary hustings, one-to-one meetings with Tory MPs and Tuesday's BBC TV debate.

Environment questions starts in the Commons, with questions on what the government is doing to tackle climate change in government contracts.

Labour's Alex Norris asks when there will be new targets against climate change.

Mr Gove says that the government has already agreed to net zero emissions from the UK by 2050, which will ensure "we leave a cleaner and greener planet for the next generation".

Eliminated leadership hopeful Rory Stewart - who was knocked out in the third ballot last night - says he will not publicly back any of the remaining contenders on Thursday.

The international development secretary says: "I will not be declaring for anyone today - but I will be voting."

Leadership hopeful Sajid Javid, who came fourth in the previous ballot, says: "I think I will be picking up some votes but these things can be unpredictable so I want to go for it."

He says he has the "strongest case" for being the one to take on Boris Johnson in the final ballot and to "win over the nation" in a general election.

Conservative leadership contender Jeremy Hunt says it’s time to “put someone forward who the EU are actually prepared to talk to” in order to get a “better Brexit deal”.

He adds: “May the best man win – and that’s going to be me."

Conservative leadership candidate Michael Gove says he is “looking forward” to a “civilised debate of ideas” should he make the final two in the leadership contest.

He came third in the ballot yesterday.

He says he is “feeling confident” ahead of today’s ballots and he has already had a “wonderful level of support” from other MPs.

It's a busy day for Conservative MPs as they enter a final two rounds of voting in order to establish the choice for their members on the next prime minister.

But, there are other events taking place in the Palace of Westminster.

MPs are about to take their seats on benches in the Commons. They'll start the day with environment and Commissioners' questions.

There's an urgent question tabled by Conservative Brexiteer Sir Bill Cash on further payments to the EU in the event of a no-deal Brexit.

Then, the government will unveil business for the week ahead in the Commons, followed by two statements on pornography age verification and export licences.

This will be followed by two backbench debates on refugee family reunion and access to justice.

The day will close with an adjournment debate on establishing a medical duty of care for sea port agents.

Today sees the final ballots in the Tory leadership race, as MPs whittle down the existing four candidates to two.

Two ballots are planned for today so far - with the first starting at 10:00 BST and results just after 13:00. The second will take place this afternoon, with the result just after 18:00.

Boris Johnson, Michael Gove, Jeremy Hunt and Sajid Javid are all vying to be leader of the party and the next prime minister.

That's where we're going to leave our live coverage for today, after the latest ballot of Tory MPs saw the number of leadership contenders cut down to four.

International Development Secretary Rory Stewart has been knocked out of the contest, having come last with 27 votes - 10 fewer than last time.

Michael Gove has closed the gap slightly with Jeremy Hunt, who remains in second place. Sajid Javid, in fourth, will join them in the next round tomorrow morning.

The frontrunner remains Boris Johnson. He now has 143 votes - 17 more than last time and as many as his three remaining rivals put together.

A fourth and - if necessary - fifth round of voting will take place tomorrow to whittle the field down to the final two, who will be voted on by Tory members.

We should know that final pair tomorrow...so do join us then.

Four Conservative MPs are still in the race to be the next Tory leader and prime minister.

Education Secretary Damian Hinds said earlier his preferred candidate, Michael Gove, has made "accelerated progress" in today's round and has “closed the gap” with Jeremy Hunt.

Meanwhile, Simon Hoare, who is supporting Sajid Javid, said there will be "conversations going on overnight" about whom MPs will vote for tomorrow.

Mr Javid, he says, is the candidate who can "take the fight" to Boris Johnson as the "agent of change" within the Conservative Party.

"If colleagues are thinking about that - how to make the Tory party look interesting in this next round - Boris and Saj is an interesting contest."

Nicky Morgan, a supporter of Michael Gove, says Rory Stewart's supporters will undoubtedly be getting a lot of calls from backers of other candidates hoping for a switch.

She says her man is gaining on Jeremy Hunt in second place and is confident he can do it.

"I'm sure there'll be lots and lots of conversations before we do this again at 10 o'clock tomorrow morning," she adds.

She says "a lot of this is about the politics - having similar positions on things like Brexit", but it's also down to "personal friendships", promises people have made to colleagues.

Rory Stewart - who is currently serving as International Development Secretary - says he appears to have "written my cabinet resignation" with his campaign.

He says he wishes Boris Johnson "the best of luck", and with a dose of "reality" and "noble vision" he can unify the Conservative Party.

He says he has not decided whom he will support among the four remaining candidates - instead saying he will now go home and play with his children.
