UK Political Turmoil Deepens as Over 80 Labour MPs Demand Starmer Resign

UK Prime Minister Keir Starmer is battling to survive a full-blown political crisis after more than 86 Labour MPs publicly called for his resignation following a historic defeat in local elections, sending UK borrowing costs to a near 30-year high.

"Either we change leader and direction now and begin rebuilding trust, or we sink with this failing project," Maryam Eslamdoust, leader of the Transport Salaried Staffs' Association, said, reflecting the growing anger among unions and backbenchers.

The rebellion has already triggered the resignations of four ministers, including Jess Phillips, and five parliamentary private secretaries. While Starmer has rejected calls to quit, key cabinet members including Home Secretary Shabana Mahmood have urged him to set out a departure timetable. In contrast, more than 100 MPs have reportedly signed a letter opposing a leadership challenge at this time.

The turmoil, which follows the Labour party losing over 1,400 council seats, plunges Britain back into the political instability that has seen four prime ministers in just five years. For investors, the crisis raises the risk of a protracted leadership contest or an early general election, further pressuring UK assets as the government’s borrowing costs surge.

The crisis escalated rapidly after the full scale of Labour's losses in the May 9 local elections became clear. Starmer, who led his party to a landslide victory in July 2024, has seen his authority evaporate. In a speech on Monday, he accepted responsibility for the "devastating" results but insisted he would not "walk away and leave the country in chaos."

His defiance has failed to quell the revolt. The number of MPs demanding his departure has swelled to over 86, more than the 81 needed to trigger a leadership contest under party rules. Prominent backbencher Catherine West is actively collecting signatures to force a vote, telling reporters it was "too little, too late" from the Prime Minister.

Cabinet Divided, Officials Resign

The pressure is most acute within Starmer's own government. Home Secretary Shabana Mahmood and Foreign Secretary Yvette Cooper have both privately told the Prime Minister he should prepare for an orderly transition of power, according to sources familiar with the discussions. In a devastating public blow, Safeguarding Minister Jess Phillips resigned on Tuesday, stating in her letter that "deeds, not words are what matter" and that she could not "keep waiting around for a crisis to push for faster progress."

Her departure followed that of Miatta Fahnbulleh and two other junior ministers, adding to the sense of a government coming apart. Downing Street has moved to replace the departed officials, but the resignations signal a deepening conviction among some that the Prime-minister's position is untenable.

Markets Price in Turmoil

The political chaos has sent a chill through UK financial markets, which had prized the stability Starmer initially promised after years of Conservative party infighting. Investors are now shunning UK government bonds, with borrowing costs surging to their highest level in almost 30 years as the prospect of increased spending under a potential new leader or a snap election looms.

"We have seen this movie before, and it ends with UK assets getting cheaper," said James Linger, a bond fund manager at Schroders. The British pound has also come under pressure. The last time Britain faced a similar rapid collapse in leadership, during the final months of the Conservative government, the pound fell sharply against the dollar.

The path forward for Starmer looks increasingly narrow. While his allies insist he will fight any leadership challenge, the open rebellion from a significant portion of his parliamentary party and key union figures suggests his time in Downing Street may be running out, regardless of his determination to stay.
