Speaking before today’s call began, Antonio Costa, President of the European Council, said the EU was “waiting with anxiety” for the outcome.
“I wish all the best for this call between President Trump and President Putin,” he said, during his joint news conference with UK Prime Minister Kier Starmer, and Ursula von der Leyen.
Costa made it clear what Europe expects from the exchange. An unconditional, immediate ceasefire, he said, was “essential".
Donald Trump’s interventions so far have injected huge amounts of uncertainty among European leaders.
They’ll be waiting nervously for some sign that the American president is willing to exert more pressure on Vladimir Putin than he has so far seemed willing to countenance.
Donald Trump’s ambivalence towards the war in Ukraine hung over today’s summit in London and the unveiling of a new UK-EU Security and Defence Pact.
The war, and Trump’s disruptive return to the White House, have been two major drivers of moves to enhance cooperation between London and Brussels.
More than three years on since Russia's full-scale invasion in Ukraine, fighting rages on. Both Ukraine and Russia have reported attempted drone strikes and shelling.
Overnight, Russia’s Defense Ministry , externalsaid it destroyed one Ukrainian drone in the Belgorod region, with another 34 drones destroyed in Crimea and western Russia’s Bryansk region. Officials say one woman in Belgorod was killed.
In the last hour, Ukraine's armed forces report casualties following a Russian airstrike on Kramatorsk in the country's Donetsk region. Earlier, they also reported "large-scale fires caused by Russian strikes" in the village of Staryi Saltiv, Kharkiv - there were no casualties.

On a broader scope, Moscow controls approximately 20% of Ukraine's territory, including the southern Crimea peninsula it illegally annexed in 2014.
Ukrainian military chiefs say assaults on the frontline have risen by up to 30% in recent weeks.
Russia’s Investigative Committee chief Alexander Bastrykin says 621 civilians have been killed since Moscow's full-scale invasion, reported on Monday by Moscow Times.

Russian state TV reports that Vladimir Putin is holding his telephone call with Donald Trump at a music school in the southern Russian resort city of Sochi.
President Putin is visiting a local education centre there today.
Right now, the two main TV channels in Russia are discussing the Putin-Trump call in their evening political talk shows.

Image source, ReutersPutin has consistently demonstrated his continued determination to continue attacking Ukraine rather than engage in meaningful peace talks.
He’s shown nothing but disdain for the peace process: ahead of the Istanbul meeting last week, he kept everyone guessing until the very last moment about who he’s going to send, and that turned out to be an insultingly low-level delegation.
The West has given Putin little reason to even start thinking about ceasing fire.
He is emboldened by Trump’s friendly rhetoric and actions, and by all the pressure the US president has put on Ukraine, rather than Russia.
And when it comes to Ukraine’s European allies, it’s been a week since the 12 May deadline set by the so-called coalition of the willing for Russia to cease fire or face crippling sanctions.
The deadline came and went, and there have been no consequences. So what is the coalition of the willing actually willing and able to do?
This may be high-stakes for Trump and Ukraine, but unless the US president comes up with new levers of pressure, Putin has little to worry about.

Image source, Getty ImagesThis is an extremely high-stakes call for President Trump, who has made ending the fighting in Ukraine one of the most important foreign policy priorities of his administration.
So far, Trump's been unable to make any progress, and his frustration seemed to boil over into outright anger during his February Oval Office meeting with Ukrainian President Volodomyr Zelensky.
In the months since then, however, Trump - who was once seemingly reluctant to criticise the Kremlin - has grown visibly exasperated with President Putin.
Just a month ago, for example, Trump took to Truth Social to "STOP", and more recently told reporters on Air Force One that he is considering secondary sanctions if necessary.
Administration officials have expressed optimism about today's call. But if Trump feels he is being taken advantage or believes that Putin is stalling, it could mark the beginning of a period in which we are likely to see more forcible language and actions from the White House.
Trump and others - notably JD Vance - have also suggested that the US could walk away from the peace efforts entirely if neither side is willing to come to a compromise.
That, however, would almost certainly be seen as a defeat for an administration which has repeatedly vowed to bring an end to the bloodshed.

The phone call between President Trump and President Putin has begun, the White House has confirmed to the BBC.
Donald Trump's call with Vladimir Putin is under way, news agency Reuters reports citing a White House official.

Image source, Getty ImagesThere was a small step forwards in diplomacy between Russia and Ukraine on Friday, as representatives from the two countries met in person for the first time since March 2022.
Despite this, there was no breakthrough on the issue of a truce, and the only agreement between the sides was for each to return 1,000 prisoners of war to the other.
Ukraine's deputy foreign affairs minister Serhiy Kyslytsya said the hostage swap was a "very good end to a very difficult day", while defence minister Rustem Umerov suggested the "next step" should be a meeting between Zelensky and Putin".
Meanwhile, Putin's aide Vladimir Medinsky said the Russian delegation were satisfied with the talks and ready to continue contact.

We're taking a look back at what was a relatively short briefing from White House Press Secretary Karoline Leavitt.
Her remarks about the Trump-Putin call were brief, and sparse on details about what the President is expected to discuss.
Leavitt's non-committal responses could be seen, partly, as a bid to avoid boxing the White House into a corner and to allow flexibility for Trump within the call.
Trump, after all, has been vowing to end the fighting in Ukraine for months now.
In February, for example, Trump and various administration officials said they believed a ceasefire could be in-place and the fighting stopped within several weeks.
That never materialised, and fighting has continued - putting the administration in the awkward place of having to "walk back" their own previous comments.
White House: Trump is 'weary and frustrated' with Russia and Ukraine
Image source, ReutersAs we've just reported, the White House says talks between JD Vance and Zelensky were "productive", we've been hearing from the US vice-president himself on board Air Force Two.
Ahead of Trump's upcoming call with Putin, US Vice President JD Vance has said that Washington recognises there is an "impasse" over talks regarding the war in Ukraine.
"I think the president's going to say to President Putin: 'Look, are you serious? Are you real about this?'" Vance told reporters aboard Air Force Two, as he prepared to depart Italy.
"Putin does not seem to quite know how to get out of the Ukraine war," Vance said, adding that if Russia is not willing to move beyond mistakes made in the past, eventually the US has to say "this is not our war".
"It's Joe Biden's war, it's Vladimir Putin's war. It's not our war. We're gonna try to end it, but if we can end it, we're eventually gonna say, You know what? That was worth a try, but we're not doing anymore."
Image source, ReutersLeavitt is now asked about US Vice-President JD Vance's meeting with Ukrainian leader Volodymyr Zelensky.
She says the meeting was "good" and "productive".
Vance has also met Pope Leo XIV in the Vatican - we have more on their talks in our news story.
During the briefing, Leavitt confirms that Vance also passed on an invite from Trump for the Pope to attend the White House.
With that, Leavitt wraps up ahead of the president's call with Putin. Stay with us for the key developments.

Trump's goal for today's call is "to see a ceasefire", Karoline Leavitt says.
She adds that the president has "grown very frustrated with both sides of the conflict".
Asked if Trump hopes to arrange an in-person meeting with his Russian counterpart, Leavitt said that the "president would certainly be open to that."
The press secretary added that "everything is on the table" in the future, including potentially secondary sanctions.
Echoing frequent comments from Trump, Leavitt has also claimed - without providing any evidence - that the war would not have started if Trump had been in the White House in 2022.

A short briefing from Leavitt on Trump's "big, beautiful" budget bill leads into questions from the media, and attention turns to Trump's call with Putin.
When asked if Americans can expect "to be done financing international wars", Leavitt says Trump is "working overtime" to try and bring peace.
She shares little in terms of what the two presidents will discuss, saying only that she did not want to "get ahead" of the call.
Leavitt confirms that following the Trump-Putin phone call there will be a statement either from the White House or from the US president himself.

Image source, ReutersOn Saturday, Trump announced his plan to speak to Putin.
In a post on social media platform Truth Social, the US President said the subjects of the call will include "stopping the bloodbath" in Ukraine and, separately, trade.
"Hopefully it will be a productive day, a ceasefire will take place, and this very violent war, a war that should have never happened, will end," he adds.
He says that following the call with Putin he will speak to Ukrainian President Zelensky and "various members of Nato".

Image source, Bernd Debusmann Jr/BBCThere's a hive of activity here at the White House ahead of today’s phone call between Donald Trump and Vladimir Putin at 10:00 EST (15:00 BST).
We haven’t heard much about the specifics of what the call with entail, but Trump had said on Truth Social that there will be a focus on stopping the “bloodbath” in Ukraine.
The call will be followed by conversations between Trump and Ukrainian President Volodomyr Zelensky, as well as some Nato allies.
It's unclear how the White House will gauge the outcome of the call, and what it believes would constitute progress. On Sunday, US special envoy Steve Witkoff said he believes the conversation will be "successful".
It's clear Trump wants the fighting to stop, and he has recently expressed frustrations with Putin.
The US president and other key officials have suggested the US could either walk away from the ongoing talks if there is not a breakthrough in reaching peace, or they could pressure Russia with further sanctions.
