Speculation is mounting within Westminster that Deputy Labour Leader Angela Rayner could be positioning herself for a future challenge to Sir Keir Starmer's leadership, with the announcement of a revealing new memoir acting as a catalyst for the rumours.
Memoir Stirs Political Waters
Reports confirmed on Friday 19 December 2025 indicate that Angela Rayner is in the process of writing a book detailing her life and political journey. The memoir will trace her path from an impoverished childhood to her current prominence as a senior figure in the Labour Party.
This personal project is being widely interpreted in political circles as more than just a retrospective. Many see it as a strategic move to solidify her public profile and narrative, a step often taken by politicians with leadership ambitions. The timing has directly fuelled intense speculation about her intentions regarding the party's top job.
Denials, Tickets, and 'Caretaker' Claims
Amid the growing chatter, several key details have emerged. There are claims that Ms Rayner might consider launching a joint leadership ticket with Shadow Health Secretary Wes Streeting, presenting a united front against the current leader.
This comes despite Sir Keir Starmer's recent public assurance that Rayner would return to his cabinet. Furthermore, Number 10 has explicitly denied suggestions that the Deputy Leader was offered the role of Education Secretary in an attempt to dissuade her from any potential bid for leadership.
The internal party tensions are underscored by reports that some Labour MPs have begun privately referring to Sir Keir as a 'caretaker prime minister', questioning his long-term hold on the position. However, allies of Angela Rayner have moved to quash the rumours, denying the existence of any formal leadership pact or that a vacancy is anticipated.
Starmer's Stance and the Road Ahead
For his part, Sir Keir Starmer has been unequivocal about his plans. He has repeatedly stated his intention to remain as Labour leader and lead the party into the next general election. He has framed the recent period as one of stable governance and future planning.
Nevertheless, the combination of a high-profile memoir, whispered discussions of alternative tickets, and murmurs of discontent from backbenchers ensures that questions over Labour's long-term leadership will persist. The situation presents a complex backdrop of loyalty and ambition within the UK's main opposition party as it looks toward future electoral battles.
