It’s been a busy day here in London as Prime Minister Sir Keir Starmer hosted a swathe of fellow leaders to discuss the state of play of the war in Ukraine.

Starmer started off his Sunday by telling the BBC that the UK and France will work with Ukraine "on a plan to stop the fighting" with Russia - and will then "discuss that plan with the United States".

After a swift stop at No10 to meet with Italian Prime Minister Giorgia Meloni, he headed to Lancaster House to greet the 18 leaders – mostly from Europe, including Ukrainian President Volodymyr Zelensky – for his Ukraine summit.

A little over two hours later, Starmer was back in Downing Street warning that “we are at a crossroads in history today”.

• Starmer announces 'coalition of the willing' to guarantee Ukraine peace
• Ukraine still 'ready' to sign US minerals deal, Zelensky says
• Was Starmer's summit enough to sway Trump?

He said the UK would be allowing Ukraine access to £1.6bn of export finance to buy an additional 5,000 air defence missiles – and the leaders had reached an understanding on four crucial steps needed to secure peace in Ukraine:

As Starmer spoke, Zelensky flew to Sandringham for a meeting with King Charles before a 90-minute chat with reporters ahead of his trip back to Ukraine.

The Ukrainian president said he still wants "the Ukrainian position to be heard" while adding his country is still prepared to go ahead with a rare minerals deal with the US despite his heated confrontation with Donald Trump in the Oval Office on Friday.

"If we agreed to sign the minerals deal, we’re ready to sign it," he told the BBC's Laura Kuenssberg.

He also suggested that he's aware of a reported joint proposal by Starmer and French President Emmanuel Macron for a one-month truce with Russia. "I'm aware of everything," he said in reply.

We'll be pausing our coverage of the latest efforts to secure a diplomatic conclusion to the war in Ukraine. Thank you so much for sticking with us today - have a great evening.

And here's our mini-photo gallery reflecting the highlights of what has proved to be a very busy news day in London.

During his sit-down with the press earlier this evening, Zelensky was asked about accepting the current line of contact as Ukraine's de-facto new border.

"Today we are talking about the first steps," Zelensky says about today's meeting with fellow leaders, saying he doesn't want to talk about them until they are down on paper.

He goes on to say that they are not talking about concessions of any kind before saying everyone needs to recognise that Ukraine will never recognise territories currently occupied by Russia as Russian land.

Zelensky ends his answer by adding that Ukraine hopes that security guarantees will make it “100% impossible” for Russia to pursue further aggression - but saying he doesn’t want to talk about the details until there are signatures on paper from Ukraine’s partners.

More now from French President Emmanuel Macron and UK Prime Minister Sir Keir Starmer and their reported proposed one-month truce between Russia and Ukraine.

In an interview with France's Le Figaro newspaper, Macron says such a truce would not - initially, at least - cover ground fighting but would be "in the air, at sea".

But he admits it would be very difficult to verify that the ceasefire was actually being respected on such a vast front line.

Peacekeepers could be deployed at a later date, the French leader also suggests before adding: "There won't be European troops on Ukrainian soil in the coming weeks."

He also suggests European countries should raise their defence spending to between 3.0 and 3.5 percent of GDP to respond to Washington's shifting priorities and Russia's militarisation.

We can bring you some more comments from Volodymyr Zelensky from his final media appearance before heading back to Ukraine.

Asked for his thoughts on today’s summit and his security guarantees goals, he says Ukraine believes its best security guarantee “is a strong Ukrainian army” - something he says he's sure Sir Keir Starmer knows too.

He says it's "important" European allies are not reconsidering Russia's role as the aggressor party, adding he's raised the issue of using frozen Russian assets to help with the reconstruction of his country again.

Ukraine’s relationship with the US will continue, Zelensky says, later adding that he doesn't think that Friday's scenes inside the Oval Office "brought something positive or additional to us as partners".

He adds that he's "sure that this situation will pass by" and that in the future, if talks are "constructive, a positive result will come".

In recent weeks, diplomatic efforts to end the fighting in Ukraine have been led by Donald Trump, speaking to President Putin and, well, at President Zelensky.

All the while, his administration has gone after its European allies; questioning their democracy, voting against them at the United Nations and today – in the form of the president’s chief enforcer, Elon Musk – saying even the US should leave the Nato military alliance.

This has left the transatlantic alliance on the brink. So today’s summit was an attempt by the prime minister both to calm diplomatic brows and stiffen diplomatic sinews.

His plan, along with the French, is to explore a new way of finding a ceasefire in Ukraine and in so doing take some ownership of the process.

Diplomats said there was clear resolve to support Ukraine but also to build on Trump’s desire to find a ceasefire.

That included more countries offering Ukraine greater security guarantees to deter Russian aggression, turning the country into what the European Commission chief Ursula von der Leyen described a steel porcupine. But Europe stepping up is only half of the story.

The Prime Minister made clear the US has to be willing to play its part. And today there were mixed messages.

The secretary of state Marco Rubio said America was ready to engage with Ukraine. But the US national security adviser Mike Waltz suggested Zelensky might have to resign as part of any ceasefire.

We've reported a little earlier that US Treasury Secretary Scott Bessent warned a deal on minerals between the US and Ukraine could not be signed "without a peace deal" with Russia.

The BBC's Laura Kuenssberg has quizzed Zelensky about the future of the agreement - noting the White House is now “making clear you need to budge somehow”.

Zelensky answers saying the minerals deal is ready for minister to sign. “It is our policy to continue what happened in the past, we’re constructive,” he continues, “if we agreed to sign the minerals deal, we’re ready to sign it.”

“The agreement that’s on the table will be signed if the parties are ready,” he concludes.

• As a reminder, Ukraine was expected to sign the deal - which would grant the US access to Ukraine's rare mineral reserves - during President Zelensky's visit to Washington but the Ukrainian delegation ultimately left earlier after a heated confrontation with Donald Trump in the Oval Office

Kuenssberg also asks the Ukrainian president about comments from French President Emmanuel Macron about a potential one-month truce between Russia and Ukraine.

French national newspaper Le Figaro reports Macron said he and Prime Minister Sir Keir Starmer have proposed the temporary cessation of the conflict "in the air, at sea".

Asked whether he's aware of the plan, Zelensky says: "I'm aware of everything."

We can now bring you fresh remarks from Volodymyr Zelensky, who's sat down with members of the media before heading back to Ukraine.

Are you willing in principle, the BBC's Laura Kuenssberg asks, to talk about conceding territory as well as in principle expressing some regret to President Trump after your heated confrontation at the White House on Friday?

While he doesn't directly address the question, he says: “I just want the Ukrainian position to be heard,” adding that he didn’t want his country’s position to be ambiguous.

But he says “we must all understand and know each other, and we must understand the red lines,” saying those red lines are not emotional, but they just happen to be there.

We can now bring you Ukrainian President Volodymyr Zelensky's reaction to his meeting with fellow leaders in London earlier today.

"We feel strong support for Ukraine, our people: soldiers and civilians, our independence," he writes on Telegram.

"We are working together in Europe to create a solid foundation for cooperation with America for the sake of real peace and guaranteed security."

"European unity is at an exceptionally high level, which has not been seen for a long time," he adds.

A little earlier, US Treasury Secretary Scott Bessent was asked if a minerals deal between Ukraine and the US is still on the table.

He tells the BBC's US partner CBS it's "impossible to have an economic deal without a peace deal".

Bessent says Ukrainian President Volodymyr Zelensky has "thrown off the sequencing" of how the minerals deal and peace deal were supposed to play out, and that it's unclear if he now wants to proceed.

"President Trump's idea for this economic arrangement was to further intertwine American and Ukrainian people and to show the Russian leadership that there was no daylight," says Bessent.

He adds that Zelensky came to the Oval Office and "tried to relitigate in front of the world".

"The place to have done that would have been in the private lunch," he says.

During his speech, the prime minister said 5,000 air defence missiles will be supplied to Ukraine.

They will be manufactured in Belfast at a factory operated by Thales, a French arms manufacturer.

The lightweight multirole missiles (LMMs) are intended to protect against Russian drone and missile attacks.

Ukrainian forces are already using LMMs with an initial order delivered late last year.

The order is much bigger, worth up to £1.6bn and will involve Thales hiring an additional 200 people in Belfast.

More reaction from other European leaders now, firstly from Poland's Prime Minister Donald Tusk.

He has posted on X to say "Europe has woken up", alongside a photograph of the leaders at the summit earlier today.

Tusk says those present "all speak with one voice about helping Ukraine, the need for close transatlantic cooperation and strengthening the eastern border".

Italy's prime minister, Giorgia Meloni, has given her reaction too, and says "the one thing we absolutely cannot afford is a peace [in Ukraine] that does not last".

She continues: "We must be very careful when assessing what is being proposed, particularly in response to this key question: could this peace be violated? Because, unfortunately, we have seen this happen in the past."

And there have been words on X too from outgoing German Chancellor Olaf Scholz, who mentions that being "transatlantic allies" in Nato remains "the key for security" in the US, Canada and Europe.

He says the alliance has been strengthened in recent years "with new members and defence spending" and that is "the path we will continue to follow in the future as well".

Dutch Prime Minister Dick Schoof, also on X, reiterates that Europe "must take a greater role in ensuring safety for our continent" and adds that "good transatlantic relations are also indispensable".

Over the past 48 hours, we've seen several pro-Ukraine marches take place in Europe and the US - including today in London as leaders met to discuss ending the war in Ukraine.

Here's some pictures from the latest demonstrations:

Zelensky not wearing a suit to a meeting with the King was always going to attract commentary, but the symbolism of his trademark informal shirt shot up following the spat in the Oval Office on Friday.

Donald Trump – who had referred to himself as king, external on social media days earlier - appeared to have an issue with it, and one conservative US reporter present at the tempestuous meeting accused the Ukrainian president of “not respecting the dignity of this office”.

Looks like King Charles has no such problems with Zelensky’s attire.

Before we heard from Prime Minister Keir Starmer, Nato chief Mark Rutte was speaking to reporters outside Lancaster House as he left this afternoon's summit and described the talks as "really positive".

He said that "more European countries will ramp up defence spending” but did not go into specifics.

Rutte described increased defence spending as "very good news" and reiterated the need for "more of a fair balance" with the US.

He also told reporters that the first step was to make sure there is a peace deal before there are discussions about how to guarantee it.

We're seeing some more pictures now from the meeting at Sandringham Estate between King Charles and Zelensky.

The pair's meeting was announced yesterday and Zelensky made his way to meet with the King after the summit of European leaders at Lancaster House, in central London.

We've just heard from UK Prime Minister Sir Keir Starmer following the summit in London where leaders from Europe, Canada and Turkey met to discuss working together for the security of Ukraine and the continent as a whole.

Starmer said "we are at a crossroads in history," and unveiled the following plans:

• The UK, France and others have agreed to work with Ukraine on a plan to stop the fighting - this plan will be discussed with the US and together they will take the plan forward
• During the summit, four points were agreed: To keep military aid flowing into Ukraine, to have Kyiv at the table for any peace talks, for European leaders to to aim to deter any future Russian invasion of Ukraine and a "coalition of the willing" will be formed to defend Ukraine and guarantee peace there
• Additionally, the UK will be giving Ukraine access to £1.6bn ($2.01bn) to buy new missiles
• Europe must do the heavy lifting in any peace deal, Starmer said, but the agreement would need US backing

We'll keep brining you analysis and reaction to the European leaders summit throughout the evening.

Ukrainian President Volodymyr Zelensky has arrived at the Sandringham Estate in Norfolk for his meeting with King Charles.

Local people, some holding Ukraine flags, gathered outside the estate to try to witness his arrival.

Finally, Starmer is asked whether he fears that the West might split over its support for Ukraine - a reference to relations between Europe and the US.

The question came after comments made earlier by Italian prime minister Giorgia Meloni, who said the West must "avoid the risk" of dividing.

Starmer says that he and Meloni share "a huge amount of common ground" on feeling that Europe and the US have to stand together.

He adds that it is important for the security of Europe that the continent works closely aligned with the US.
