GB News said thirty-year gilt yields climbed by 0.09 percentage points to 5.76 per cent, moving closer to the 5.79 per cent level reached last week, and sterling weakened as much as 0.73 per cent against the dollar to $1.3506.

Newsday reported that Starmer was fighting for political survival after Labour’s disastrous local election results, with dozens of Labour lawmakers calling on him to resign.

Newsday added that Starmer could be forced out if one-fifth of sitting Labour lawmakers, or at least 80 of them, agree to back a lawmaker to challenge him, while so far no formal leadership challenge had been triggered.

GB News said political tensions inside Government intensified overnight ahead of a crucial cabinet meeting scheduled for 9.30am on Tuesday morning, as senior Labour figures called for Starmer to resign.

Palace, resignations, and pledges

As Starmer’s leadership crisis deepened, Buckingham Palace privately asked whether King Charles III should proceed as planned with the ceremonial state opening of parliament on Wednesday, according to people familiar with the matter.

POLITICO.eu quoted one of those people saying, "The Palace view is 'we do not want to be any part of this conversation — do not bring us into it,'" as the king’s team sought to avoid any impression of political involvement.

Newsday reported that Deputy Prime Minister David Lammy urged lawmakers to step back from calling for Starmer to step down, telling reporters, "Let’s get on with the business of running this country."

Newsday also said a junior minister became the first member of Starmer’s government to quit on Tuesday, with Dr. Zubir Ahmed writing that “door after door your name was specifically cited as the driving reason” for Labour voters in Scotland turning away from the party.

POLITICO.eu described the state opening as the formal start of the new parliamentary session, noting that unless parliament is formally convened again, MPs and members of the House of Lords cannot meet there to debate priorities, question ministers or pass new laws.

King’s Speech and what’s at stake

Starmer’s survival fight is set against the backdrop of the King’s Speech, with the BBC saying King Charles III will unveil the government’s agenda for the year ahead on Wednesday as Starmer fights for his future in Downing Street.

The BBC reported that the King’s Speech is expected to include more than 35 bills and draft bills, including on immigration, the NHS and police reforms, and it said the route to potentially nationalising British Steel remains part of the plans.

BBC also quoted Starmer saying people expect the government to "get on with the job of changing our country for the better," while noting that whether he is in position to deliver the planned laws remains to be seen.

In parallel, GB News said bond investors were increasingly concerned that any Labour leadership contest could result in a shift towards higher public spending and borrowing under a more left-leaning successor.

Newsday added that Starmer insisted he has no intention of resigning, even as more than 100 Labour lawmakers reportedly signed a statement rejecting a leadership contest and urging party members to "work together to deliver the change the country needs."
