24 prisoners who have been held in six countries have been released in the largest East-West prisoner swap since the Cold War.

The exchange involved 16 detainees from the West - including Americans Evan Gershkovich, Alsu Kurmasheva and Paul Whelan - and eight who are returning to Russia.

Eastern Europe correspondent Sarah Rainsford has been in regular contact with some of those who have now been swapped, and gives us her reaction and security correspondent Gordon Corera explains what Russia is getting out of this and how it compares to previous exchanges.

And we hear from Evan Gershkovich’s colleague at the Wall Street Journal, Gráinne McCarthy, about what happens next for the journalist who spent 16 months in Russian custody.

Today’s episode is presented by Jamie Coomarasamy and Vitaly Shevchenko.

As the dust settles on the Nato summit in Washington, we decode the diplomatic agreements and ask how much help it offers Ukraine. Matthew Savill from the London-based defence think-tank RUSI breaks down what the commitments might mean for Ukraine on the battlefield, as well as the geopolitical implications of Joe Biden’s continuing stumbles.

Kyiv has now suffered its worst week this year with 33 killed and 125 injured following the devastating set of strikes across Ukraine, including on a children’s hospital in the capital. We hear one young mother’s search for her daughter, who she feared had been buried under the rubble.
