The police have launched a criminal investigation into Peter Mandelson in the wake of a fresh cache of Epstein files being published by the US government. These appear to show that Mandelson passed sensitive information to Jeffrey Epstein and his associates while he was a government minister and encouraged a US banker to try to intimidate then-chancellor Alistair Darling.

What had been a deeply embarrassing situation is now even more serious. And despite making moves to distance himself from Mandelson, Keir Starmer has questions to answer – including how much he knew about all this before appointing Mandelson as his ambassador to Washington.

Mandelson resigned from the House of Lords yesterday over the scandal, which is a relief to Starmer, who doesn’t have the power to remove him. But Mandelson will remain Lord Peter Mandelson of Foy and Hartlepool. Constitutional expert Stephen Clear explains that as much as he’d like to, the prime minister cannot remove Mandelson’s title.

Scientists, meanwhile, are calling for urgent action on free-living amoebas – potentially dangerous organisms that can get into our water systems. One can even attack human brains. But in more reassuring news, this weeks Strange Health podcast reveals that cracking your knuckles, your neck or any other body part won’t harm you.
