Angela Rayner is set to publish her memoirs next year, detailing her rise in politics and departure from government this year, which is worrying news for Keir Starmer. The former Deputy Prime Minister will publish the tell-all autobiography in the second half of 2026, amid ongoing rumours of a planned leadership coup.

The book will cover her early life, including her impoverished childhood and difficult upbringing, to her resignation from the second-in-command position in Sir Keir’s government. Despite the circumstances of her departure from high office, she remains both popular and influential among Labour MPs and members. According to the betting markets, her housing tax row has not dampened her hopes of one day replacing Sir Keir Starmer.

Odds published this morning by Oddschecker said she is the second-most likely to replace the Prime Minister should he be toppled next year, after Health Secretary Wes Streeting.

The book was subject to a bidding war among several publishers; however, it was ultimately acquired by The Bodley Head, a division of Penguin.

Ms Rayner is reportedly yet to decide on a title for the highly-awaited memoir.

A friend of the former Housing Secretary told the Guardian: “There’s been huge interest from publishers. This won’t be your standard politician’s memoir. It will be authentically Angela and in her own voice.”

Alice Skinner, editorial director at Ms Rayner’s chosen publishers, said: “We are so delighted and proud to be publishing Angela Rayner. Her book will be unvarnished and upfront – you can expect her authenticity to shine through – and an empowering vision for a fairer, kinder society that will enable everyone to flourish.

“It will spark change, one reader at a time.”

Yesterday it emerged that the Prime Minister is already strategising to avoid a leadership challenge after what is widely expected to be a disastrous showing in the May elections.

The Prime Minister will confirm the next King’s Speech for May 12 or 13, just a week after voters go to the polls.

Advisors in No. 10 believe that having the King unveil the government’s agenda for the coming year so soon after the local elections will force plotters to back down.

According to the BBC, one government source argued: “It will be much harder for somebody to challenge the PM and say we need to go in a different direction when the King is about to come to parliament to announce what we’re doing for the next year.”

Many Labour MPs have earmarked the local elections as Keir Starmer’s final chance to prove he can turn things around, and should he fail they will move to replace him.
