Starmer warns Labour leadership battle would trigger “chaos” as Streeting challenge looms

Political tensions inside the Labour Party escalated dramatically on Wednesday after Prime Minister Keir Starmer privately warned colleagues that any leadership contest would destabilise both the government and the party.

The warning came during meetings with ministers and Labour MPs at Parliament following growing speculation that Health Secretary Wes Streeting may soon challenge Starmer for the party leadership.

According to reports from Westminster, Starmer told colleagues that allowing the party to descend into a leadership battle would “plunge us into chaos,” insisting that such a contest would severely damage the government’s ability to function.

The growing uncertainty overshadowed the ceremonial State Opening of Parliament and the unveiling of the government’s legislative agenda by King Charles III.

Instead of focusing on the King’s Speech and Labour’s proposed programme for the coming parliamentary session, political attention shifted almost entirely to Starmer’s increasingly fragile position following the party’s disastrous local election results last week.

Labour suffered heavy losses across England and failed to secure control of the Welsh Senedd for the first time in nearly three decades, intensifying criticism of Starmer’s leadership from within his own party.

Supporters of Streeting reportedly expect the health secretary to formally launch a leadership challenge as early as Thursday, although Streeting himself has so far avoided publicly confirming his intentions.

Under Labour Party rules, a challenger would need the backing of at least 20 percent of Labour MPs — currently 81 members — to trigger a formal leadership contest.

The crisis deepened further after multiple ministers resigned earlier this week while dozens of Labour MPs publicly urged Starmer either to step down immediately or announce a timetable for his departure.

At the same time, more than 100 Labour MPs reportedly signed a statement backing the prime minister, highlighting the deepening internal divisions within the governing party.

Speculation has also intensified around potential alternative leadership contenders.

Allies of Defence Minister Al Carns reportedly believe he could enter the race if a contest is triggered, although he is viewed as an outsider compared with more established figures.

Meanwhile, supporters of Andy Burnham are said to be exploring ways for the Greater Manchester mayor to return to Parliament through a possible by-election should the leadership battle become prolonged.

Several Labour MPs, however, publicly denied reports that they were preparing to vacate their seats to make way for Burnham.

As political uncertainty deepened inside Westminster, Chancellor Rachel Reeves was reportedly engaged in private efforts to persuade MPs not to rally behind Streeting in order to avoid a damaging internal conflict.

Starmer has meanwhile continued publicly promoting the government’s legislative agenda, pledging to build what he described as a “stronger, fairer Britain” following the King’s Speech.

But behind the scenes, pressure on the prime minister continues to mount as Labour grapples with internal unrest, electoral setbacks and growing questions over its political direction ahead of the next general election.
