The next question comes from a Channel 4 journalist who asks Starmer if he has become used to being called prime minister.

"Yes, I am getting used to it," Starmer replies. "I am very happy to be called Keir or prime minister."

He's also asked when people at home, feeling the pinch, can notice things getting better, to which Starmer reiterates that the work has started.

"Different change will be delivered at different speeds. I can't pretend we are going to fix things over night."

Starmer uses an example of prisons and says he can't "build one overnight".

Keir Starmer says that he is going to have to make tough decisions and "make them early".

"We will do that with a raw honesty," he adds.

He goes on to say that prisons are an obvious example of an issue that needs to be addressed, "where other parts of the system are broken".

"We will take the tough decisions," he reiterates.

The prime minister is asked about Health Secretary Wes Streeting's comments that the NHS is "broken".

He replies saying the government is going to have to take tough decisions on public services early.

But he adds that these remarks are "not a prelude" to announcing a tax which is not in the manifesto.

Starmer is now asked by Sky news if he can name one concrete thing he can promise voters that he will deliver in his first 100 days.

Starmer replies by saying that the government's mindset has already changed.

When submissions come to him from the cabinet, he says "the principle is country first, party second - that change has already happened".

On the election outcome, he says, "it is a clear mandate, we argued for change and we got that mandate".

He says he was pleased to see the exit poll: "I didn't believe it...and like everyone else, I stayed up to watch every single result come in."

Starmer turns to questions from journalists in the room. First up is BBC Political Editor Chris Mason who asks Starmer if he has unpacked, found his way around Downing Street and whether Labour can deliver concrete change.

"I am restless for change," Starmer says, acknowledging his appointments of James Timpson and Sir Patrick Vallance to positions in his government.

However, he admits that "it is going to take time".

"We have got plans in place. I did not want to get ahead of the election result but we have been planning for months to hit the ground running."

He turns to the question about finding his way around Downing Street, saying he has a "basic understanding" of the rooms he has been in so far.

"No, we are not unpacked quite yet," he adds.

Starmer says he will travel to Washington DC for the Nato summit on Tuesday and he has already spoken to a number of world leaders since taking office.

The prime minister calls security and defence the "first duty" of his government.

He adds that he spoke to Ukrainian President Volodymyr Zelensky yesterday, and says the UK will continue to support Ukraine.

Starmer now moves on to talk about his party's mandate to deliver economic growth.

He plans to meet with the metro mayors on Tuesday including non-Labour metro mayors.

His door is always open, he says, adding that his government will work with them "regardless of the colour of their rosette".

Starmer says he will set off tomorrow to visit all four nations of the United Kingdom.

"First to Scotland, then to Northern Ireland, then to Wales and then back to England where I will meet the first ministers," he says.

The prime minister says he wants to establish a way of working across the UK "which will be different to what we have had in recent years".

Starmer begins by saying the work of the new government has already started.

He says as the "dust settles" after the election, it is clear what is expected of the government and its mandate to change the country.

Starmer says there is an expectation that the new government will "do things differently" and that he used his first cabinet meeting to set out what he expects of his ministers in terms of standards and delivery.

He will chair new "mission delivery boards" as prime minister to ensure each department is performing to his expectations.

More ministerial appointments will follow this afternoon, he adds.

There are a lot of questions for an incoming government, from priorities to policies.

This is a chance for journalists to ask some of them.

A source close to Starmer told me earlier that it was also about "accountability".

We're told the new PM wants to show a change of style in Downing Street.

But don't expect a return to monthly news conferences like Tony Blair used to do. There's no plan for that at the moment.

Sir Keir Starmer has just started speaking at his first news conference as prime minister.

We will also bring you what he says on this page.

Our political correspondent Henry Zeffman spotted Anneliese Dodds at this morning's cabinet meeting in a seat reserved for the minister of state for development – an appointment that has not yet been formally announced.

That job was held by Andrew Mitchell in the last government and shadowed by Lisa Nandy.

However, Nandy has been moved to the culture department after Thangham Debbonaire – who was expected to take that role – lost her Bristol seat to the Green Party.

Dodds had been shadowing the women and equalities brief, but it's unclear who will now take on that role.

Prime Minister Keir Starmer will be speaking at a news conference from Downing Street in about 10 minutes.

Labour wants to "make Britain secure at home and strong abroad", says new Defence Secretary John Healy.

Addressing the defence ministry for the first time, Healy highlighted "serious problems" the world faces, such as "war in Europe, conflict in the Middle East, growing Russian aggression, increasing global threats".

He said the armed forces have been underfunded for 14 years, but Labour is "totally committed" to 2.5% of GDP for defence spending, Nato, the nuclear deterrent and support for Ukraine.

"Our mission is to make Britain secure at home and strong abroad, with the guiding principle of one defence," he added.

Some comments to bring you from the new environment secretary who says "it will take years" to tackle the sewage and nature crises.

As he took on the brief, Steve Reed said: "It is the privilege of my life to be appointed as the Secretary of State For Environment, Food and Rural Affairs.

"There is no sugar-coating it: we face a crisis point.

"Record levels of sewage in our rivers, lakes and seas. Nature is dying. Confidence amongst farmers at the lowest on record."

He insisted the "work of change begins now".

Health Secretary Wes Streeting has told reporters the first cabinet meeting was "very good".

He adds: "We're getting to work straight away."

Streeting was joined by Business Secretary Jonathan Reynolds, who described the meeting as "superb" as they departed No 10.

Last night, the new health secretary said the NHS was "broken" and it would take a team effort to turn the health service around.

Labour's first cabinet meeting has just wrapped up and some of the MPs have been seen leaving No 10. The newly appointed ministers met to discuss what Starmer has called the government's "first steps" towards delivering change.

We are going to hear more from the new prime minister later this afternoon, but here's a reminder of what those plans involve:

• Sticking to tough spending rules in order to deliver economic stability
• Setting up Great British Energy, a publicly owned clean power energy company
• Cutting NHS waiting lists by providing 40,000 more appointments each week – funded by tackling tax avoidance and non-dom loopholes. New Health Secretary Wes Streeting described the NHS as "broken" on his first day on the job
• Tackling illegal migration by launching a border security command to stop the gangs arranging small boat crossings

• Providing more neighbourhood police officers to reduce antisocial behaviour and introducing new penalties for offenders
• Recruiting 6,500 teachers - paid for through ending tax breaks for private schools

While Labour's new cabinet is meeting at No 10, let's see what some former Tories who lost their seats are saying about the future of the Conservative Party.

Miriam Cates, who lost her seat of Penistone and Stocksbridge to Labour, says the party needs to "take our time" and not chose a new leader straight away.

There needs to be a “serious period of humble reflection” on why we lost so “drastically”, she tells BBC Radio 4's Today programme.

Cates says Tory voters were "lost to Reform", and she thinks many Tory supporters didn't vote.

"We need to win those people back".

Damian Green, former senior cabinet minister, who lost his seat in Ashford, echoes that sentiment.

"You can’t just add the Reform vote to the Tory vote, we’ve got to win a lot of those voters back," he says.

The party can do that by "demonstrating competence" and by having policies that appeal to a "broad Conservative framework".

He adds that it would be "utterly disastrous" to bring Reform leader Nigel Farage into the Tory party as they would lose "millions of votes on the other side".

Former Labour Foreign Secretary Dame Margaret Beckett has told the BBC she is "angry" and "sad" that some of her party's candidates were defeated by candidates opposed to Labour's stance on Gaza.

Labour saw its vote challenged in some areas by independents who campaigned heavily on the situation in the Middle East.

Beckett tells BBC World Service's Weekend Programme: "I could despair at hearing well-meaning people talking such nonsense about how 'to help the people in Gaza, I will do X, Y and Z', when it will make not a scrap, not an atom of difference to any individual in Gaza - or indeed to the pursuit of peace in Gaza.

"It makes me makes me angry, actually, not just sad, to hear nonsense talked and then well-meaning people make silly mistakes and put somebody in place who will have no effect at all, in place of somebody who could be a very effective actor in the pursuit of peace."

She says she hopes the new government will be "getting involved behind the scenes" to push for a two-state solution.

As we've just been reporting, Prime Minister Sir Keir Starmer is holding his first Cabinet meeting.

Flanked by his deputy PM Angela Rayner to his left and Cabinet Secretary Simon Case to his right - he started by telling his ministers: "We have a huge amount of work to do, so now we get on with our work".
