By-elections: Badenoch congratulated Starmer on being the other party leader to win a by-election this week, referring to Burnham's win in Makerfield and the Conservative win in Aberdeen South. Starmer said he was "very pleased" with Labour's new MP.

Defence Investment Plan (DIP): Badenoch pressed the PM on the DIP, referencing the resignation of Defence Secretary John Healey. Starmer said his government has delivered the biggest sustained boost to defence spending since the eighties, and the DIP will take that even higher.

Badenoch blames Reeves: The Tory leader spent much of PMQs targeting the chancellor. She said Reeves "killed economic growth" and claimed Starmer wouldn't "be in this mess" had she found money for the DIP.

...and Phillipson: Badenoch asked Starmer if he has been "let down" by the education secretary given the number of teachers has gone down. The PM maintained he's "so proud" that she's sitting there beside him.

A nice moment there as veteran Tory bruiser Desmond Swayne throws everyone with a question about a little boy called Jim “who ran away from home and was eaten by a lion”.

Starmer responds with an anecdote about Swayne welcoming the holidaying Starmer family to his New Forest constituency with a bottle of champagne.

Beyond the heated rhetoric from the front benches, there is some sympathy for the PM’s plight.

Plaid Cymru MP for Dwyfor Meirionnydd, Liz Saville-Roberts, says Keir Starmer's resignation comes "close on the heels of the end of Labour's 100 year dominance in Wales".

"People simply didn't feel his party stood up for them," she says, calling this part of the PM's legacy.

Referring to a tradition of leaving notes on your desk for successors, she asks whether the PM will pass on the message that "democratic choices including those of devolution can't be dismissed".

Starmer says he'll leave a note saying what his government delivered for Wales was the "largest ever devolution settlement".

Ed Davey takes a swipe at Kemi Badenoch for the tone of her attack on the PM.

The Tory leader and her team are having none of it.

Davey is being far more sympathetic towards the outgoing PM.

Davey turns his attention to the ongoing heatwave, asking the prime minister whether he will warn his successor against listening to the Conservatives or Reform UK and back Liberal Democrat plans to "cut bills and tackle climate change".

Starmer thanks Davey for raising climate change, which he describes as "one of the most significant challenges of our time".

The prime minister says it used to be "common ground" that climate change was a "generational challenge", but adds that it is a "shame that in order to chase Reform votes" the Conservatives have "changed their minds".

"I will always maintain that we must be global leaders on climate change and we always will be," Starmer adds.

Next up, Leader of the Liberal Democrats Ed Davey says he hopes the government will implement "in full" the recommendations of a new report into maternity care.

• For context: the Ockenden Maternity Review – the largest maternity review in NHS history - was published a short while ago. It details how failings led to baby deaths and avoidable harm. You can read more about this in our separate live page.

Davey says he wants to recognise "how difficult it was" for the prime minister to make his resignation statement on Monday, and says it's a reminder that "we are all human and it's something that everyone should remember".

He asks if Starmer will urge Burnham to adopt the Liberal Democrats' plan for a growth and defence partnership with Europe.

Starmer says he's "very proud" to have "reset" Britain's relationship with the EU, which is "in the best interests of our country".

Badenoch says Starmer has "made many mistakes, otherwise he wouldn't be going".

She says he has also been let down by his energy secretary, who is "killing industry", "by a chancellor killing jobs, by backbenchers who don't understand being in government is about tough choices".

She says Starmer has "U-turned again and again to appease them".

Starmer says because of Labour's decisions the country is moving "in the right direction", listing achievements such as improving workers' rights, lifting children out of poverty and standing with Ukraine.

The prime minister on his way out, Kemi Badenoch sought to broaden her critique to other senior Labour folk - not least Andy Burnham, who she described witheringly as a "pair of eyelashes and a black T-shirt".

Chancellor Rachel Reeves and Education Secretary Bridget Phillipson were also in Badenoch’s crosshairs.

Starmer’s defence of Phillipson, and his passionate pride in her life story, rising from poverty to the cabinet, really stood out - given how often Starmer’s critics point to what they see as his often sterile public demeanour.

Badenoch says if the education secretary knew so much about poor children, she wouldn't have given them fewer teachers.

Referring to the reaction in the chamber, she says she's "never seen this much excitement" on Labour's benches, accusing them of cheering loudly while they've stuck "400 knives" in the prime minister's back.

She says Starmer tried to cut welfare but the MPs behind him stopped him. "Does the PM feel betrayed by the people he got into Parliament?" she asks.

The Speaker interjects, asking people to think about the language they use and calling for "decorum" and "respect".

Starmer says he's proud of all his MPs, saying they picked up the party, turned it around and won a landslide victory in 2024.

He adds that Badenoch "won't even talk about" the Tories' "failure after 14 long years".

Badenoch asks Starmer again "if it's all so fantastic, why is he resigning?", adding that it is "very generous" of the prime minister to stand up for his ministers "because they didn't stick by him".

She then asks MPs to raise their hand if they think Education Secretary Bridget Phillipson is doing a good job. There is laughter on her side of the benches when Badenoch says not even Phillipson raises her hand.

She asks the prime minister whether he agrees that he has been "let down" by the education secretary, given that the number of teachers has gone down.

Starmer responds by saying that Phillipson grew up in poverty and represents "an incredible story of social mobility and success", saying he is "so proud" that she is sitting there.

Badenoch pushes back that Reeves is the one who "let [Starmer] down", saying that she "snatched the winter fuel payments" and put together a "disastrous budget" that "killed economic growth".

She also accuses Energy Secretary Ed Miliband of letting Starmer down by "putting up bills and killing jobs", and says he's now allied with Andy Burnham.

Starmer cites a fall in NHS waiting lists, new renters' and workers' rights and the lifting of "half a million children out of poverty".

He says this is all evidence that he is "leaving the country in better shape" than he found it, which is "more than can be said" for previous Conservative governments.

Rachel Reeves is stony-faced as Kemi Badenoch turns her fire on the chancellor.

Tory MPs are enjoying this.

Badenoch says Starmer wouldn't "be in this mess" if Reeves had found money for the Defence Investment Plan.

She adds that the prime minister gave Reeves the second most important job in Britain and she wouldn't even stand beside him on Downing Street during his resignation speech.

Starmer defends Reeves' record, saying she pulled the country out of austerity and noted other economic improvements he's put to her name.

"With this chancellor we have the right economic plan," he says.

Starmer responds by saying he's "very pleased" with Labour's new MP Andy Burnham.

"Can I also say to her [Kemi Badenoch] in Gorton and Denton, the Tories got 1.9% of the vote," he says. "Can I congratulate her because in Makerfield they got 2.2%, just edging past Count Binface," he adds.

Starmer says it will take the Tories "500 years" to get back into power at that rate.

Meanwhile, he says his benches have delivered the biggest sustained boost to defence spending since the 1980s, referencing £270bn being spent over this parliament.

The Defence Investment Plan will take that even higher, he adds, saying the government will have it published before the Nato summit.

Kemi Badenoch begins by congratulating Starmer for being the "other party leader" who won a by-election last week, but jokes she is "much happier" with her new MP than he is.

• On the same night Andy Burnham became the new Labour MP for Makerfield, Douglas Lumsden won for the Conservatives in Aberdeen South

Badenoch moves on to defence spending, referencing the resignation of Starmer's defence secretary John Healey, who quit government over the long-awaited defence investment plan.

She says Healey accused the prime minister of being "unable" and the treasury "unwilling" to fund the defence of our country. "What changed?" Badenoch asks.

A Conservative heckler shouts out ‘Andy?’ when the prime minister mentioned the meetings he was having today.

It led to a smile from Sir Keir Starmer - who replied "not today!"

This is set to be a pretty weird PMQs - one of the last for Keir Starmer, before he stands down.

There is much speculation about whether Andy Burnham will show up. There is no sign of him so far.
