There are now six contenders vying to succeed Boris Johnson as Tory leader and prime minister after the first round of voting today
Rishi Sunak, Penny Mordaunt, Liz Truss, Kemi Badenoch, Tom Tugendhat and Suella Braverman all received the support of more than 30 MPs, meaning they will be included in a second ballot tomorrow
Nadhim Zahawi and Jeremy Hunt bowed out of the race after failing to reach the threshold
The second round of voting by MPs will see the field narrowed again, with the least popular candidate knocked out regardless of the support they receive
It comes as a snap poll of party members showed Penny Mordaunt has the most support among card-carrying Tories
Boris Johnson appeared at PMQs where he vowed he would leave No 10 with his "head held high"
Meanwhile, the government is tabling a motion of confidence in itself after refusing a Labour call for a showdown on the prime minister's future.
And then there were six: Who's left in the race for PM?
There are six people left vying to take over from Boris Johnson as Tory leader. So who are they and what do they stand for?

Boris Johnson loyalist Nadine Dorries is claiming the prime minister's downfall is the result of a "coup" staged by Tory MPs.
In a pre-released clip from tonight's BBC Panorama, the culture secretary says she was "stunned" that some of her colleagues wanted Johnson out of No 10 less than three years after a landslide victory.
The "anti-democratic nature of what they're doing alone was enough to alarm me", she tells presenter Laura Kuenssberg.

Quotes of the day: Thatcher, smears and a time for unity
Leadership contenders have been out in force looking to shore up their support ahead of the first round vote - and now six will proceed to Thursday's second ballot. Here are some of the key quotes of the day:
Quote Message: We will cut taxes and we will do it responsibly. That's my economic approach. I would describe it as common-sense Thatcherism. I believe that's what she would have done." from Rishi Sunak

What happens next? Your guide to the next stage of the contest
PA MediaCopyright: PA Media
Six candidates have qualified for the second round of voting tomorrow.
Rishi Sunak, Penny Mordaunt, Liz Truss, Kemi Badenoch, Tom Tugendhat and Suella Braverman will all be in Thursday's ballot.
Tory MPs will vote again between 13:30 and 15:30 BST.
The result of the second round will be announced at 17:00 and the candidate who finishes sixth will be eliminated.
From now on though, there will be no minimum threshold of votes for contenders to reach to progress further.
In theory, the process will then continue with further votes of Conservative MP daily from next Monday - and a single candidate eliminated each time - until just two are left.
A decision on which of them will replace Boris Johnson as prime minister will then go to the party's membership - thought to number about 200,000 - with the winner announced on 5 September.
But the number of MPs' votes could be shortened if candidates drop out or merge campaigns.
Tory party vice-chair quits role to campaign for Mordaunt
Hemel Hempstead MP Sir Mike Penning has resigned as Conservative Party vice-chairman to campaign for Penny Mordaunt in the leadership contest.
He has told Sky News: "As vice-chair I was unable to declare who I would want to vote for so I stepped down this afternoon.
"Penny has all the attributes we're looking for now, she's very down to earth, she's served her country as defence secretary and in the Royal Navy, and particularly in my constituency she will go down very well."
Expect allegiances to start shifting
Six candidates remain and one big question - what happens to those 43 votes allocated to the two candidates eliminated?
Expect as soon as this evening a shift of allegiances and a remoulding of this campaign, yet again.
The working assumption here at Westminster is that Rishi Sunak will get one of the two tickets to go into the final two to be decided by Conservative party members.
There is now a battle for that second ticket - between Liz Truss and Penny Mordaunt. And this evening at least, Penny Mordaunt has the upper hand.
Braverman 'has all to play for'
Attorney General for England and Wales Suella Braverman came sixth in the first round of the contest with 32 votes.
minimum threshold to proceed to the next round was 30 votes, and Braverman is the lowest placed candidate to remain in the contest.
But in a tweet, Braverman is showing no sign of being about to drop out of the race.
MP Miriam Cates is backing her. She tells the BBC we've "got a lot of work to do" but "it's all to play for" in tonight's hustings.
She says Braverman will impress with her "passion, authority, professionalism and detail".
Cates says Brexit is not finished and Braverman is well placed to deal with problems that remain like the Northern Ireland Protocol (which sets out trading arrangements for Northern Ireland after Brexit).
Badenoch says Tories 'must stand as the party for change'

Kemi Badenoch has also been sharing her reaction to making it into the second ballot in the Tory Party leadership race.
The former equalities minister, who came fourth securing the backing of 40 MPs in today's vote, has just tweeted gratitude for her colleagues' support.
"To win the next election and deliver Conservative solutions to today’s problems, our party must stand as the party for change," she says.
"I have the conviction, the courage, and the clarity of thought to deliver that change."
Hunt-McVey ticket 'clearly not the right one'
Esther McVey, Jeremy Hunt's prospective deputy prime minister, has acknowledged the combination of the pair was "clearly not considered the right one" after Hunt was knocked out of the contest.
In a statement, the backbench MP says she is "extremely grateful" to Hunt for "putting so much faith in me"
McVey adds she hopes colleagues "adopt the spirit" of what their campaign tried to achieve, which she says was "putting together a programme the party can unite behind to win the next election".
Quote Message: The remaining candidates all have immense talent and strengths. I will take some time speaking with them all before deciding who to vote for in the remainder of this election process."

Zahawi will not make 'further intervention' in contest
Chancellor Nadhim Zahawi has said he does not "intend to make any further intervention" in the leadership contest, following his failure to make the second round.
In a letter posted on Twitter, Zahawi writes he will continue to work leading the Treasury with "total focus" and thanked the supporters of his campaign.
Quote Message: "I am very grateful for the support of colleagues in this leadership election and to Conservatives up and down the country who have got behind me and sent me best wishes. Clearly my part in the contest has now ended.

Brexit stalwart Villiers supporting Sunak
Former Cabinet minister Theresa Villiers announces she is backing Rishi Sunak, saying he's "the best person to take the country through difficult economic circumstances".
She describes the first round result as "a really good start" in a "closely fought election".
Villiers is a committed Brexiteer. Most other Brexiteers have attacked Sunak's record on taxes, but Villiers says the former chancellor is a tax cutter and she has "real confidence" he can win the next general election.
Sunak camp upbeat about first round result
Team Sunak say "he’s landed a quarter of the party with eight candidates in the field".
The former chancellor has won 88 of the possible 358 votes in today's opening ballot of Conservative MPs.
Tugendhat 'has real momentum' - Damian Green
Tom Tugendhat supporter Damian Green says he is "absolutely still in this" and there's "real momentum there".
"Tom is offering a clean start," he states, and he suspects that Tugendhat - who came fifth in today's ballow with 37 votes - will now pick up some of Jeremy Hunt's supporters.
"Rishi has come ahead," he says, and he is the "most known name in this election," he says others are "scrapping for other slots on the ballot paper".
He says northern MPs are supporting Tom Tugendhat, and "as the debate continues" then people will start focusing on whether or not tax cuts "will be inflationary", he says.
Green says cutting duty on fuel, as Tom Tugendhat proposes, would be anti-inflationary, he says it's "extraordinary" that the UK doesn't currently have a long term plan for growth.
Another Tugendhat supporter, Anne-Marie Trevelyan, says that the MP is putting across a "positive" message, and it's still "all to play for".
At the scene: Zahawi supporters make phone calls
Political Correspondent, BBC News
I've just spotted some of those who supported Nadhim Zahawi on the
phone in hushed tones outside the result venue.
It’s exactly these kinds of MPs who the remaining candidates
will want to be tapping up to try and convince them to join their side.
These negotiations will play a crucial role over the next few
Mordaunt nipping at Sunak's heels after strong showing
BBC political correspondent
Penny Mordaunt was modest as she left the room, saying “I’m
honoured” in response to her strong second place.
That, and the relatively narrow gap between her and Rishi Sunak are the main headlines from the first vote.
One Mordaunt backer in the room said her healthy showing
in the first round indicated the need for the membership to be allowed the chance to have their say on her.
One backbencher not revealing who they’re backing
suggested Sunak’s lead was hardly overwhelming.
Another backing Liz Truss said
it shouldn't be taken for granted that the former chancellor would make the
All eyes are on Jeremy Hunt and Nadhim Zahawi’s backers
now to see who they support.
And there’s a feeling that the pressure's building
on Suella Braverman to endorse another candidate, possibly Liz Truss.
Sunak 'feeling great' about opening round result
Former chancellor Rishi Sunak - seen by many as the frontrunner - has topped the first ballot of Conservative MPs with 88 votes.
He tells the BBC he feels “great” about the result.
Sunak resigned as chancellor last week.
Simon Clarke: Liz Truss is the sensible option
Liz Truss supporter Simon Clarke says "Liz is part of a pack of three candidates... who have serious momentum going into the days ahead".
He says "Liz is the sensible option" and the right of the party need to get behind a single candidate.
Not changing the "underlying economic plan" would mean that the UK can do tax cuts, he adds, "under the government of Boris Johnson", but there is "more headroom to be achieved" to allow reductions in taxation.
People on the right of the party will "have to think" about previous statements Penny Mordaunt has made, says Clarke, adding that he himself doesn't agree with Mordaunt on the issue of trans rights and her views on women.
