Donald Trump says he's 'disappointed' that Vladimir Putin keeps knocking down buildings in Kyiv despite all the great conversations they are having about ending the war in Ukraine, as the First Lady Melania Trump keeps pointing out to him.

So the president is ramping up the threats, offering 'top-of-the-line' weaponry to Ukraine and promising severe tariffs on Russia if there's no ceasefire within 50 days.Is that enough to get Putin to the negotiating table? Or just escalating an intractable conflict? And is Trump even serious about bumping his bestie in Moscow?On the latest episode of The Fourcast, Matt Frei is joined by Channel 4 News’ International Editor Lindsey Hilsum and historian and author Anne Applebaum.

Keir Starmer and Emmanuel Macron have announced a "one in, one out" migration deal which would see France send one asylum seeker with a British family connection to the UK for every migrant sent back.

Under the terms of the deal, up to 50 people a week could be sent back to France.

But what impact will the new deal really have?

In today's episode of the Fourcast, Senior Political Correspondent Paul McNamara speaks to Charlotte Khan from Care4Calais and Peter Walsh, senior researcher at the Migration Observatory, about whether we can really expect to see a change to the number of people crossing the English Channel by small boat.

What comes first - a peace deal or a peace prize? The war rages on in Gaza - another 40 Palestinians were killed overnight in Israeli airstrikes, but Israel's Prime Minister Benjamin Netanyahu has been unable to thrash out a ceasefire deal despite two days of talks in Washington, though he did nominate Donald Trump for the Nobel peace prize.

Meanwhile in Gaza families continue to struggle for food and water amid the constant bombardments and with an aid system that is failing to deliver. Israeli officials say they are working with the UN and other bodies to “ensure necessary aid crosses the border”. So who is to blame for this catastrophe? And what needs to be done to alleviate it?

In this episode of The Fourcast, Cathy Newman speaks to James Elder, global spokesperson for UNICEF, the United Nations agency providing humanitarian aid to children worldwide. He is just back from Gaza - his fifth visit to the territory since the war between Israel and Hamas began in October 2023.
