Shockwaves are surging through British politics after a dramatic by-election in Gorton and Denton. In this episode of Talking Politics, Robert and Tom unpack what the Greens’ victory means for Labour - was Starmer “nuts” for not taking the left-wing party more seriously? And will he have to step down? With cries of dodgy practices and unfair treatment, they also discuss ‘family voting’ and whether it was an issue in the contest.

In a week that started with Peter Mandelson's arrest, and will end with a crucial by-election for the PM, Tom and Robert discuss whether Mandelson's arrest will prove terminal for Starmer.

They unpack why Commons Speaker Lindsay Hoyle warned the Met that Mandelson was a flight risk - triggering his arrest.

The former Business Secretary denies any wrongdoing, and says his overriding priority is to cooperate with the police investigation and clear his name.

But will Mandelson's arrest define the PM's premiership?

Tom and Robert discuss what could happen in this week's by-election in Gorton and Denton and how it could be the most important result of the PM's career.

Meet Senator Mark Kelly: distinguished Navy Pilot, NASA astronaut and Democratic Senator for Arizona, but when Kelly urged service members to refuse illegal orders, Donald Trump said he should be punished “by death”.

Trump later clarified, "I'm not threatening death, but I think they're in serious trouble."

Now Kelly's contemplating a run for the Presidency himself.

Tom sits down with the Senator to discuss the death threats and lawsuits that have followed, why he believes you need to "stand up to bullies" and his advice to the UK: "You don't want somebody like him in charge of the UK."

Is the US a reliable ally? If he was still serving, would he obey orders to invade Greenland? And what lessons can the UK learn from the MAGA movement?
