Why has Volodymyr Zelenskyy reshuffled Ukraine's military leadership at a crucial moment in the war against Russia?

As Kyiv ramps up its long-range drone campaign deep inside Russia, Ukraine's president has appointed General Mykhailo Drapatyi to lead the country's armed forces. Supporters say he's the innovative commander Ukraine needs for the next phase of the conflict—but why make such a significant change when the war appears to be swinging in Ukraine's favour?

On this episode of The Fourcast: Indicators, Matt Frei and Mark Urban examine what Zelenskyy's military shake-up signals, whether Ukraine is rewriting the rules of modern warfare, and if drones can continue to shift the balance against Russia. They're joined by Orysia Lutsevych, Head of the Ukraine Forum at Chatham House, to discuss the challenges facing Kyiv, what Vladimir Putin may do next, and the wider security picture, including Houthi attacks in the Red Sea and the emerging US-Saudi nuclear agreement.

Andy Burnham is Britain's new prime minister.

On his first day in Downing Street, he promised the biggest changes to Britain in 40 years, unveiled his vision for government and began assembling his cabinet. But what do those first decisions tell us about the kind of Prime Minister he wants to be?

In this episode of The Fourcast, Anushka Asthana examines Burnham's first speech and the challenges waiting in his in-tray. Can he rebuild trust in politics? How different is ‘Burnhamism’ from the Starmer years?

Joining Anushka today are Neal Lawson, a close ally of Burnham’s who co-founded the influential left wing group Compass, political strategist Peter Hyman, who was at the heart of the Downing Street operation in the Blair years and a senior adviser to Keir Starmer in opposition, and Political Editor at the i Paper, Caroline Wheeler. 

The World Cup final is here. But could this tournament be remembered more for its politics than its football - from Donald Trump's travel restrictions, to soaring ticket prices and growing criticism of FIFA's relationship with the White House, controversy has followed this World Cup from the very beginning.

At the centre of it all is FIFA president Gianni Infantino. Once elected promising to clean up football's governing body after the Sepp Blatter era, he's now facing mounting criticism from across the game. So, has Infantino gone too far? Could his grip on FIFA finally be weakening? Or is he more powerful than ever?

So, can the US gain the upper hand? Will more US bombs and bullets really help? And has this whole episode proven that the memorandum of understanding, which was meant to end the conflict, was destined to fail.

Britain is getting hotter. But is the country ready?

After another record-breaking heatwave, experts estimate that thousands of excess deaths may already have been linked to the extreme temperatures. From overheating homes and buckling railways to schools, hospitals and reservoirs struggling to cope, questions are growing over whether Britain's infrastructure was ever designed for the climate it's now facing.

So what do these latest attacks tell us? Is diplomacy finished? Could Israel escalate its military campaign? And what does renewed instability mean for shipping through the Strait of Hormuz and the wider global economy?

Nigel Farage is trying to take back control of the scandal around his finances. Facing mounting questions and a parliamentary standards inquiry which could prompt a recall petition and by-election he has pre-empted it all and forced one himself. He's pitching it as the people against the establishment - the chance to flick two fingers at the media and political opponents, and prove he's done nothing wrong. But will it work? Will it resolve any of the questions about who gave him money, why and why he didn't declare it? Is this a genius masterstroke by a brilliant tactician, or a desperate stunt by an angry man that could backfire? And is it effectively an admission that the inquiry will find he broke the rules? On this episode of The Fourcast, Krishnan Guru-Murthy was joined by the former Conservative now Reform supporting commentator Tim Montgomerie, former Reform Deputy Leader turned Farage critic and rival Ben Habib, who has shared a platform with far-right activist Tommy Robinson, and from More in Common the pollster Luke Tryll.
