'Labour rivals want to rejoin EU' and 'survival of the fittest'

The Sunday Telegraph warns that "Britain's Brexit wounds" could be reopened because it says both Andy Burnham and his leadership rival, Wes Streeting, favour Britain rejoining the European Union. The paper understands that Reform UK will make "Brexit betrayal" a theme of its by-election campaign in Makerfield. The Sunday Times says Streeting's announcement that he wanted to rejoin the EU had "electrified the race to succeed Sir Keir Starmer". It says his words signal an end to what it calls "the longstanding omerta" among senior Labour figures who want to see closer alignment with Brussels.

Andy Burnham has spoken to the Sunday Mirrorin what it calls his first in-depth interview since he declared his plan to return to Parliament. It says he has laid out his vision for the country, and that a Burnham administration would take stronger public control of essentials such as energy and water, introduce proportional representation and greatly increase the number of council houses built. TheMirror says the need to unify the left is "urgent".

The Observer describes the prime minister attacking Wes Streeting, by telling insiders that the health secretary damaged the government "when he never had a plan to win" any leadership ballot. The paper also claims that Sir Keir's relationship with Energy Secretary Ed Miliband has been gravely damaged by recent events, saying Miliband chose not to urge the party's soft left to support No 10, when the challenges emerged to the prime minister's leadership.

Dan Hodges writes in the Mail On Sunday that Sir Keir Starmer has told close friends that he intends to stand down and set out a timetable for his departure. A cabinet minister is quoted in the article as saying "he realises the current chaos is unsustainable", and will leave in a "manner of his own choosing".

The Sunday Express claims that Iranian spying operations on UK soil are the responsible for the highest number of hostile state activity investigations. A senior counter-terror officer tells the paper that there are record levels of investigative casework on terror plots, espionage and state-level threats to individuals.

The Sun on Sunday says armed police protecting the royal family have been accused of falling asleep on the job. The paper says dozens of officers are being investigated, and says that it's also been claimed that some clocked on, then failed to attend their posts. Sources tell theSun it's "embarrassing". The Met has told the paper it has launched an urgent investigation to look into the allegations.
