The Fourcast

The government is weighing up whether or not to follow in Australia’s footsteps and ban social media for under-16s. Supporters argue that online safety efforts have failed and that children are being exposed to increasingly harmful content. Critics warn that a ban would isolate young people, let tech companies off the hook, and create a dangerous cliff-edge at 16.
Companies across the Big Tech sector have consistently said that protecting children is a priority, as is reducing the spread of disinformation on their platforms.
In today’s episode of The Fourcast, Cathy Newman speaks to Professor Kaitlyn Regehr, author of Smartphone Nation, and digital journalist Sophia Smith Galer, about what a ban would really achieve, whether regulation can ever keep pace with the platforms, and how algorithms amplify harm in ways that governments, and parents, struggle to control.

It was hoped the fall of Syria's former dictator Bashar al-Assad would usher in a period of stability, unity and perhaps - eventually - democracy.

But now the country enters a new and unpredictable phase as President Ahmed Al-Sharaa tightens his grip on power.In the north-east of the country the Kurds were the West’s key ally against Islamic State.

Now their control in the region is collapsing after days of fierce battles with government forces. A tentative ceasefire is in place but the fallout is far from clear, including the fate of thousands of ISIS prisoners and their families who were in Kurdish-controlled camps.Regional powers like Turkey and Iran, as well as China, Russia and the West are also jostling for influence.

Could these developments finally bring a period of calm and stability in Syria or just open the door to new dangers?

As Donald Trump marks a year back in office, his threats against Europe and hard-line trade policies are pushing his allies to the edge - while China and Russia, once considered America’s enemies, watch on with apparent glee.
And if the UK once thought flattery was the best form of defence, the president has put paid to that with potentially crushing tariffs and a swipe at Keir Starmer’s Chagos Islands deal - an agreement he had supposedly signed off on.
So how do we make sense of a global future in flux?On this episode of The Fourcast, Jackie Long was joined by geopolitical strategist Peter Zeihan.

Donald Trump wants Greenland - and he’s willing to use tariffs to get it.

If European allies refuse to sell, the US president has threatened to escalate trade penalties, weaponising economic pressure rather than military force. The proposal has sparked alarm across Europe, with some leaders calling for the EU to deploy its so-called “trade bazooka” in response. UK Prime Minister Keir Starmer has warned that a trade war benefits nobody.

So is this just bluster - or the opening shot in a new phase of transatlantic economic conflict? And what would a trade war over a sparsely populated Arctic territory mean for the global economy?

On this episode of The Fourcast, we’re joined by Mark Leonard, Director of the European Council on Foreign Relations, speaking as he travels to the World Economic Forum in Davos, and our Economics Correspondent Helia Ebrahimi is in the studio to break down the economic stakes.

It’s been quite the week in Westminster. A sacking, a defection, and a deepening crisis on the right. Robert Jenrick’s move to Reform has capped off a dramatic few days for the Conservatives. While Nigel Farage has celebrated the moment, calling it a historic realignment of centre-right politics in the United Kingdom, the Prime Minister has described the Conservative Party as a "sinking ship".
So what does this mean for the future of the Conservatives? And what does Jenrick’s defection mean for Reform - is there a real possibility that Reform could win the next election?
