Key Points
- Britain’s government is facing weeks of uncertainty after Labour manoeuvring failed to remove Prime Minister Keir Starmer, but a leadership contest now appears likely.
- Starmer has vowed to fight on, despite a bruising week in which a Cabinet member resigned and dozens of MPs publicly called for him to quit.
- Health Secretary Wes Streeting resigned and said he had lost confidence in Starmer’s leadership, intensifying pressure on the prime minister.
- Greater Manchester Mayor Andy Burnham has signalled he wants to return to Parliament and could emerge as a leadership challenger if he secures a Commons seat.
- The leadership race is delayed for now because Burnham must first win a by-election in Makerfield, where a Labour MP resigned to create the vacancy.
- Labour’s local and regional election losses last week deepened doubts about Starmer’s judgment, vision and leadership.
- Investor concern over political instability has already hit the pound and pushed up government borrowing costs.
- Party supporters are urging rivals to pause, warning that an open contest could distract from the cost of living crisis and help Reform UK.
Why is Keir Starmer under pressure?
London (Britain Today News) May 15, 2026 — Britain’s government has entered a period of acute uncertainty after a week of Labour infighting failed to force Prime Minister Keir Starmer out, yet strengthened the sense that a leadership contest is now only a matter of time.
The pressure on Starmer has been building for days, but the rebellion became impossible to ignore after his party’s poor performance in local and regional elections and the resignation of a senior Cabinet minister.
The central problem is no longer just whether Starmer can survive the immediate challenge, but whether his authority has already been fatally weakened within his own party.
That question now dominates Westminster, with MPs, ministers and ambitious rivals all positioning themselves for what could become a long and bitter contest.
What triggered the latest crisis?
The immediate crisis was sharpened by Wes Streeting’s resignation as Health Secretary, a move that followed weeks of speculation and gave the anti-Starmer camp a prominent figure around whom to rally.
Streeting said he had lost confidence in the prime minister’s leadership and argued that the government lacked direction on domestic issues.
His resignation did not just add political pressure; it also confirmed that dissent inside Labour had moved from whispered frustration to open revolt.
Streeting’s letter was sharply critical, saying that where vision was needed there was “a vacuum” and where direction was needed there was “drift”.
He also complained that Starmer’s approach had become too heavy-handed towards dissenting voices, a criticism that resonates with MPs who feel ignored by the leadership.
The resignation arrived after a weekend and week of jockeying in which ministers and backbenchers alike were increasingly discussing the possibility that Starmer could be forced out.
Did Labour’s election losses change everything?
Labour’s poor results in last week’s local and regional elections are widely seen as the key political turning point.
The party lost heavily to Reform UK on the right and the Greens on the left, undermining confidence in Starmer’s strategy and judgement less than two years after Labour’s landslide general election win.
That result gave critics inside the party fresh ammunition and encouraged speculation that a leadership challenge would eventually become unavoidable.
The numbers also reinforced a wider narrative that Labour is failing to connect with voters on everyday concerns.
The losses emboldened internal critics who believe Starmer has lost his political momentum.
The party’s supporters, however, argue that replacing him now would only deepen the crisis and hand further advantage to Reform UK.
Who could challenge Starmer?
One of the most prominent possible challengers is Andy Burnham, the popular Mayor of Greater Manchester.
Burnham has long been seen as a figure who could unite parts of Labour that feel alienated by Starmer’s style and political direction.
His name has gained further traction after Labour lawmaker Josh Simons resigned his seat to create a route back to Westminster for Burnham.
Burnham must first win the special election for Makerfield before he can return to Parliament and formally enter any leadership contest.
That by-election is shaping up to be a difficult test, because Reform UK performed strongly in the area during the recent local elections.
Burnham has already acknowledged the challenge, saying he does not take “a single vote for granted” and will work hard to win back trust in the constituency.
Is Wes Streeting now a contender?
Streeting’s resignation has made him an even more important figure in the leadership drama, even though he stopped short of formally declaring himself a candidate.
His move was widely interpreted as an opening shot in a possible contest and a signal that he no longer believed Starmer could carry the party forward.
However, Streeting also suggested that Starmer should step aside to allow a broader field of candidates to debate Labour’s future.
That wording matters, because it places Streeting in the middle of the debate without forcing him to commit immediately.
It also leaves room for others, including Burnham, to make a case for leadership.
For now, Streeting’s decision has been more significant for what it says about Starmer’s vulnerability than for any clear declaration of his own ambition.
How serious is the economic fallout?
The political turmoil is already being felt in financial markets.
Reuters reported that government borrowing costs rose and the pound weakened as investors reacted to the renewed instability in Westminster.
The pound has also fallen against the US dollar this week, adding an economic dimension to the leadership crisis.
This matters because it shows the dispute is not confined to party politics.
Markets typically dislike uncertainty, and the prospect of a drawn-out leadership battle can unsettle investors as much as voters.
The longer Labour remains consumed by internal conflict, the harder it may be for the government to project stability or focus on economic priorities.

What happens next?
The next phase depends heavily on whether Burnham can secure the Commons seat that would allow him to stand.
After that, Labour’s National Executive Committee would determine the timetable for any leadership election, and the most recent contest lasted three months.
That means uncertainty could continue well into the summer, even if no formal challenge is launched immediately.
For now, Starmer’s allies are urging the party to stop the infighting and return to governing.
Housing Secretary Steve Reed called on colleagues to “take a breath” and focus on delivery, warning that a divisive contest would distract from issues such as the cost of living crisis and could help Reform UK.
But the political mood in Labour appears tense, and the question is no longer whether the issue exists, but how quickly it becomes decisive.
Why does this matter now?
The stakes are unusually high because the crisis comes less than two years after Labour’s huge election victory.
That makes the current turmoil not just a personnel dispute but a test of whether the party can translate electoral power into stable government.
It also raises doubts about how much time Starmer has left if both senior figures and rank-and-file MPs continue to lose confidence in him.
Tim Bale, a politics professor at Queen Mary University of London, said the message of the week was that Labour had effectively decided Starmer would have to go, and that he would need to be replaced quickly by someone better able to connect with the public.
That assessment captures the scale of the moment: a government still in office, but already behaving like a leadership contest has begun.
