TV tonight: Prue Leith and her Tory MP son debate assisted dying | Television

Prue and Danny’s Death Road Trip

9pm, Channel 4

“I wish all it took was a crumpet to make him agree with me.” Prue Leith is for assisted dying, while her son Danny Kruger – a Conservative MP – stands against UK legalisation. In this thoughtful film, they hear both sides of the story, visiting people in places where it’s legalised, including a woman whose parents chose to die together. Hollie Richardson

Hair? Cracking. Heir? Lacking. That about sums up Marie’s precarious position in 1780 as the revisionist historical drama wraps up its first season. A looming naval conflict with England threatens the usual Versailles horseplay but even dopey King Louis senses danger when a sexy Swedish count swoops in. Graeme Virtue

9pm, ITV1
