AI is increasingly being used to find vulnerabilities, exploit networks and carry out cyberattacks - but how autonomous are these systems really?

On this episode of The Fourcast, Matt Frei asks whether we are approaching a world where AI agents can conduct cyberattacks with little or no human intervention. Could an AI maintain access to a network, evade attempts to shut it down or even copy itself?

Matt is joined by AI safety expert and author of Considerations on the AI Endgame, Dr Roman V. Yampolskiy, and Katie Moussouris, founder and CEO of Luta Security and a former contributor to the US government's ‘Hack the Pentagon’ programme.

They discuss the latest AI hacking incidents, whether governments need tougher regulation, who should be responsible when AI causes harm, and whether AI could ultimately become both the biggest cyber threat - and the best defence against it.

The war in Ukraine appears to have entered a new phase, as Kyiv has launched increasingly ambitious long-range strikes deep inside Russia, put mounting pressure on Crimea and sought to bring the war closer to ordinary Russians and Vladimir Putin. 

But now the Kremlin is hitting back hard. In a missile attack on Kyiv this week, at least 17 people were killed. Now there’s reports of a Ukrainian plane in Leipzig, Germany, being targeted by an explosive-laden drone. It’s not clear who was behind the attack but reporting suggests it could be Russia. So are we witnessing a dangerous new phase of escalation? 

On this episode of the Fourcast Indicators, Matt Frei and Mark Urban are joined by economist Timothy Ash from Chatham House’s Russia and Eurasia programme.

Just a few months ago, Nigel Farage and Reform UK looked unstoppable. After sweeping the local elections and topping opinion polls, many believed Reform was on course for government. But has the momentum already begun to fade?

A string of controversies - including police investigations, questions over party finances, and a £5 million donation from a Thailand-based cryptocurrency billionaire - has put Reform under growing pressure. With the party slipping in the polls, are these scandals finally cutting through with voters, or is this just another setback Farage will survive?

On this episode of The Fourcast, Matt Frei is joined by Tim Ross from Politico, former Reform UK spokesperson Gawain Towler and Labour strategist Claire Ainsley to examine what's gone wrong for Reform, whether Andy Burnham has given Labour a route back to power, why the Greens are also losing ground, and what the latest polling tells us about the future of British politics.

After around 50,000 migrants crossed into Spain’s North African territory of Ceuta, far-right politicians across Europe quickly branded the events an "invasion." But with most migrants already returning to Morocco and UK illegal boat crossings dropping to a five-year low—down 43% compared to 2025—what is actually driving the debate around European border control?

On this episode of The Fourcast, Matt Frei is joined by Director of the Migration Observatory Madeleine Sumption, Director of Politics at Ipsos Keiran Pedley, and Austrian migration expert Gerald Knaus.

They discuss whether the incident in Ceuta could drive a new surge for the far-right across Europe, how the UK could be affected and if immigration is still the hot topic for voters.

Despite his job seemingly looking assured just a few weeks ago, Gianni Infantino’s position as President of FIFA is now in jeopardy.

With the footballing federations of Europe, North America and Asia all rejecting Infantino’s plans to sell off part of the World Cup to private investors, pressure is piling on Infantino. Even the new Prime Minister Andy Burnham says Infantino is the “wrong man” to lead FIFA.

On this episode of The Fourcast, Matt Frei is joined by Channel 4’s Sports Reporter, Jordan Jarrett-Bryan, as well as Abiola Ijasanmi the former Chief Operating Officer from the Confederation of African Football.

They discuss whether Infantino has badly mis-read the situation and - could he actually could be forced out of this job?

The war between the United States and Iran has spread across the Middle East. 

Fresh strikes in Saudi Arabia, Iraq and Egypt, alongside escalating Houthi attacks on international shipping, have raised fears that the region is entering a dangerous new phase. With Washington intensifying its military campaign and Iran relying on its network of allied militias, is this becoming a wider regional war?

On this episode of The Fourcast: Indicators, Matt Frei and Mark Urban are joined by Professor Madawi al-Rasheed from the London School of Economics Middle East Centre. They discuss why the Houthis are stepping up attacks, whether Saudi Arabia is being pulled into the fighting despite its efforts to avoid it, how Iraqi militias could become a new flashpoint, and whether the US has a long-term strategy, or is being drawn into another prolonged Middle East war.

Is there still a path to de-escalation, or are we witnessing the beginning of a conflict that could engulf the wider region?

Social care is the thorny issue which politicians have failed to solve for decades.

Today though, the new Prime Minister Andy Burnham put it back on the political agenda as he called for a ‘National Care Service’, saying that social care in the UK is “as unfair” as the healthcare system in the US.

On this week’s episode of The Fourcast, Matt Frei is joined by the former Conservative Work and Pensions Secretary Damien Green, Professor Richard Humphries who is a Senior Policy Advisor at the Health Foundation and the Liberal Democrat MP and Chair of the Health Select Committee Layla Moran. 

They discuss why the current system is not fit for purpose, why previous efforts at reform have failed and whether Andy Burnham could be the one to finally solve it.

As thousands of people are forced to flee their homes amid devastating wildfires in France, Spain and Scotland, the climate emergency seems closer to people’s lives than ever.

Despite this, governments around the world are seemingly rolling back their efforts to end the fossil fuel pollution that is driving the climate emergency.

On this episode of The Fourcast, Matt Frei is joined by environmentalist George Monbiot,  Professor Liz Bentley from the Royal Meteorological Society and Fiona Macklin, Head of Climate at Apolitical.

They discuss what it will take to finally get politicians to start taking global heating  seriously. And whether even when disaster is staring us in the face, if we as a people are really ready to make the changes necessary?

Months after many of his ‘Liberation Day’ tariffs were declared illegal by the Supreme Court, Donald Trump has announced a fresh wave of tariffs against dozens of countries.

This time, using the allegation of “forced labour” by America’s trading partners, Trump is hoping his new tariffs will be less open to challenge in the courts.

But what will the impact be on American consumers already hit hard by the war in Iran? And can anyone take Trump’s trade policy seriously, when it can all change in an instant?

On this episode of The Fourcast, Matt Frei is joined by Australian-American economist Justin Wolfers, as well as Financial Times columnist and co-author of the book How to Win a Trade War, Soumaya Keynes.

The US and Saudi Arabia have reportedly signed a landmark deal that could pave the way for a Saudi nuclear programme, sparking fears it could eventually allow the Gulf kingdom to develop its own nuclear weapon.

President Donald Trump has denied that the agreement permits Saudi Arabia to enrich uranium, and says any deal is dependent on Riyadh joining the Abraham Accords and recognising Israel, a move many experts say remains unlikely.

Meanwhile, tensions in the region have escalated after Houthi attacks on Saudi ships in the Bab el Mandab strait pushed oil prices higher. Trump has warned that further attacks could trigger “major military punishment” against Iran and the Houthis.

On this episode of The Fourcast, Matt Frei is joined by Channel 4 News foreign affairs correspondent Jonathan Rugman to examine the US-Saudi nuclear deal, the growing confrontation with the Houthis, and what it means for the future of the Middle East.

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.
