On Friday, Ukrainians woke up to the news that the home of presidential chief of staff and top peace negotiator, Andriy Yermak, was being searched by anti-corruption authorities.

Although they didn’t accuse him of wrongdoing, by the evening he had submitted his resignation. So how damaging could the downfall of such a close ally be for President Zelensky, and what could it mean for peace talks?

Victoria and Vitaly are joined by Ukraine correspondent James Waterhouse to discuss the reaction in Kyiv and beyond.

We also hear the thoughts of journalist and author Simon Shuster, who interviewed Mr Yermak for the Atlantic the day before his shock departure.

And, as an American delegation meet counterparts in Moscow, we look at reports that US special envoy Steve Witkoff has been coaching the Kremlin on how to deal with Donald Trump.

Today’s episode is presented by Victoria Derbyshire and Vitaly Shevchenko.

The producer was Laurie Kalus. The technical producer was Dafydd Evans. The series producer is Chris Flynn. The senior news editor is Sam Bonham.
