Turning now to the Labour MP for Bedford, Mohammad Yasin.

He says "too many innocent people are still dying everyday" in Gaza and asks the PM what more pressure he can apply to bring about an urgent ceasefire.

Starmer says he and the foreign secretary have set out the urgent need for a ceasefire to Israeli PM Benjamin Netanyahu.

He also raised the issue with world leaders at the Nato summit he attended shortly after taking office, he says.

The Scottish National Party's Westminster leader congratulates Starmer on "ending Tory rule" - joking that they're "too close for comfort" now that they sit on the same side of the Commons.

He asks about the two-child benefit cap vote brought by the SNP last night, saying the policy "forces children into poverty" and pointing out that former Labour PM Gordon Brown supports scrapping it.

Labour's says it wants to repeal the cap but the government is not financially able to do it immediately.

In response to Flynn, Starmer says the last Labour government lifted children out of poverty and so will his.

He says he has set up a child poverty strategy, which includes breakfast clubs and abolishing no fault evictions, and then attacks the SNP record on child poverty in Scotland.

We're onto questions from backbenchers now.

Emma Lewell-Buck from Labour asks whether the PM will consider supporting a special tribunal with statutory powers, to examine the nuclear testing programme.

Starmer commits to ensuring a meeting is arranged between her and the relevant minister.

Ed Davey presses the PM on social care, asking Starmer if he thinks there's a "once in a century" opportunity to fix social care and help the NHS, after "a once in a century election".

He suggests a cross-party commission on social care to address "this urgent matter".

Starmer responds saying "he's right, it is a crisis" but "not the only crisis" inherited by Labour.

He adds his government wants to create a national care service, which will not be easy, but aims to start the first steps.

Liberal Democrat leader Ed Davey asks Starmer about the "scandal over the Carer's Allowance payment" - citing a constituent called Andrea who was earning less than £7,000 a year to care for her elderly mother.

Davey says she was then hit with a £4,000 bill from the Department for Work and Pensions, asking Starmer if he will meet with him and carers to discuss the situation?

Starmer thanks him, describing Davey as a "tireless campaigner for carers" and jokes he's glad he is wearing a suit, rather than a wetsuit - after the events of the election campaign.

On the substance, Starmer says there is a "more severe crisis than we thought" in public finances and the government needs to "review the books" - to jeers from the opposition benches.

He adds the government will work with the care sector and across the house to create a national care service.

Starmer responds to a question from Kim Leadbeater and uses it to pay tribute to her sister Jo Cox, who was murdered in 2016 while serving as an MP.

He says the whole House misses her and that he knows she would have played a big part in this Labour government.

Starmer also welcomes their parents, who are watching from the public gallery.

We will always have more in common than divides us, he adds.

Starmer replies to the question on national security by describing it as "essential", and security as the "first duty of government".

He says he will endeavour to keep the opposition notified and updated on national security matters.

Sunak describes the “dangerous and uncertain world” that we now “sadly live in”.

He says he knows first-hand how important it is that a PM can use their prerogative power to quickly respond to “protect” British national security - sometimes without giving the house notice.

Sunak welcomes the support he previously received from Starmer - assuring him the opposition will support him if he takes similar action in the future.

He asks Starmer whether he thinks such powers are essential.

Starmer says the fighter jet programme is a really important move, with significant progress made on it already.

He adds that the government wants to build on that progress and he has had discussions about the matter.

Sunak uses now asks about the Tempest fighter jet programme, which he calls "crucial" for building alliances around the world.

He asks if the new PM will continue discussions with Saudi Arabia, which has express interest in the jets.

Starmer replies be describing the House as "united" on the question of sanctions.

He says these are important issues as we move forward.

Sunak - still on the subject of Ukraine - says he hopes Starmer will see there is a “sound and established legal basis” to go further on sanctions, and seize Russian assets - and use them to fund reconstruction in Ukraine.

He asks Starmer to confirm if he will take this work forward.

Sunak next asks Starmer about his meeting with the German Chancellor Olaf Scholz on the side-lines of the Nato summit earlier this month.

He asks whether Starmer raised the “issue” of Germany “perhaps providing long range missiles” to Ukraine - just as the UK, US and France have done.

Starmer responds by saying he spoke with his German counterpart at Nato and Ukraine was a strong theme.

He urged allies to provide further support for the Ukrainian people, which was "well received", he adds, before saying there was "unanimity" at the summit.

Sunak then says he welcomes the message of support for Ukraine from the recent Nato summit which Starmer attended.

He asks if Starmer agrees that Russia's "fatuous" claims on Ukrainian territory should not act as a block to Ukraine joining Nato.

Starmer says he wholeheartedly agrees and it is for Nato allies to decide who is a member of the military alliance.

He adds that Ukrainian President Volodymyr Zelensky was pleased at the transition statement.

Prime Minister Keir Starmer replies by thanking Sunak for raising a question in a way that maintains the unity of the House of Commons.

He assures Sunak that he is talking to Ukraine about their needs in dealing with Russian aggression.

Starmer adds he will continue to reach out to opposition parties going forward.

Sunak echoes Starmer's words on the Kent attack and Team GB, joking British Olympians probably won't want his advice on "how to win", prompting laughter in the Commons.

Sunak's first question as leader of the opposition is on the subject of Ukraine. He says the UK has led the way on providing arms

He asks Starmer to pledge to listening to Ukrainian requests on further support and offers his support in opposition for the government on this matter.

Keir Starmer has opened his first PMQs as prime minister by sending his “thoughts” to an Army officer, stabbed in uniform near barracks in Kent yesterday.

The soldier, in his 40s, is in hospital in a serious but stable condition, according to Kent Police.

A 24-year-old man was arrested on suspicion of attempted murder shortly afterwards.

The Home Office says the stabbing is not believed to be terror-related.

The PM goes on to wish Team GB good luck in the Paris Olympic Games.

The prime minister is now standing at the dispatch box, which means today's session is about to begin.

I’m sitting in the reporters’ gallery waiting for the start of Sir Keir Starmer’s first Prime Minister’s Questions.

Labour’s cabinet ministers are gradually taking their seats on the front row of the government bench in the House of Commons, waiting for their leader.

Earlier this week Starmer accidentally referred to Rishi Sunak as “prime minister”. Now he’ll have to get used to answering the questions, rather than asking them.

It’s the first glimpse we’ll get of how he handles the theatre and scrutiny of the weekly question session.

And it will be particularly interesting to see how his MPs react after seven Labour MPs were suspended last night for voting against the government.

Those seven MPs will be expected to sit alongside the Conservatives, Lib Dems, SNP, independent, and other opposition parties, facing the 400 or so Labour MPs who, until last night, were their colleagues.

Midday is almost upon us, which means it's time for Prime Minister's Questions.

And it's not just any old PMQs, it's the first of the new Parliament and the first in 14 years to have a Labour prime minister answering the questions.

Taking on Starmer is interim Tory leader Rishi Sunak, who will today lead the inquisition from the opposition benches.

(There's been a fair bit of musical benches since the last PMQs on 22 May. You can get a sense of the new look of the Commons here.)

As always, we'll bring you all the key lines from the session here, along with analysis from our correspondents in Westminster.
