The past week has seen international diplomacy turned upside down as the US began talks with Russia to end the war in Ukraine. The decision to exclude Ukraine - and Europe - from these talks led to an emergency summit in which European countries sought to establish some influence over the process.

But with the US and Ukrainian presidents embroiled in a dispute that led to President Trump calling President a “dictator”, is their relationship beyond repair? And will Ukraine have any say over the terms of a peace deal?

Newscast, Americast and Ukrainecast gathered in the studio for a special collaboration to unpack the enormous shift in international politics that’s unfolding.

President Trump has launched a fresh attack on President Zelensky, calling him a "dictator" and saying he has done a "terrible job".

Zelensky earlier accused the US president of "living in a disinformation space" created by Russia.

Victoria and Vitaly analyse how this diplomatic row is playing out.

And Victoria speaks to Russia’s ambassador to the UK, Andrei Kelin.

European leaders have met in Paris for an emergency summit on the war in Ukraine.

Leaving the meeting, German Chancellor Olaf Scholz called discussions on sending peacekeeping troops to Ukraine "premature" and "inappropriate". Earlier UK PM Keir Starmer said he was ready to send such troops from the UK if and when the war ends.

So could we see European boots on the ground in Ukraine? Matthew Savill, from RUSI, is in the studio to discuss whether it’s possible, and what this might look like.

We also look ahead to the meeting tomorrow between Russia's Foreign Minister Sergei Lavrov in Saudi Arabia with US Secretary of State Marco Rubio.

What’s been the reaction in Ukraine to President Trump’s plans to end the war, following his phone calls with Vladimir Putin and Volodymyr Zelensky? We hear from Kyiv mum Iryna and 27 year old account manager Andrew.

And we assess what role Europe could play going forward, following a busy day of diplomacy at a Nato defence chiefs summit in Brussels.

In a pivotal day for the war in Ukraine, Donald Trump has agreed to ‘work together’ with Vladimir Putin to end the conflict. Immediately after the call with Putin, Trump spent an hour on the phone with Volodymyr Zelensky.

Earlier in the day, the new US defence secretary Pete Hegseth told a meeting of the Ukraine Defence Contact Group in Brussels that it was unrealistic that Ukraine could return to its pre-2014 borders and he ruled out NATO membership for Ukraine.

BBC Security Correspondent, Frank Gardner joins Victoria and Vitaly to discuss the latest developments.

‘I'd love to hear more about what's actually happening in the war now. Where are the lines stable, where is Russia still advancing, where have the Russians slowed?’ That’s a message we got from one of our listeners earlier in the week, and we thought we’d answer these questions and more.

We get a sense of what’s happening along the frontline in Ukraine right now with Matthew Savill, director of military sciences at RUSI, and we hear from a soldier whose day job is to drop bombs on Russians using drones.
