Labour is facing an extraordinary rift at the top of government. Health Secretary Wes Streeting has strongly denied claims that he is plotting to overthrow Prime Minister Keir Starmer, saying that attacks are a sign of a toxic culture at Number 10. 

The story erupted after an anonymous briefing suggested Streeting could be preparing a leadership bid - a claim he has strongly rejected. But the row raises bigger questions: how loyal is the Cabinet? Who is really pulling the strings in No 10? And what does this internal drama mean for public trust and the Labour government’s ability to deliver?

In this episode of The Fourcast, Krishnan Guru-Murthy is joined by Labour strategist and commentator, John McTernan, who was Tony Blair's political director, the pollster and director of Merlin Strategy Scarlett McGuire and the author and Guardian columnist Zoe Williams.
