Key takeaway

Starmer goes as caretaker prime minister, leaving Labour to pick his successor on a compressed timetable.

Keir Starmer resigned as Labour leader and prime minister on 22 June, four days after Labour held Makerfield, telling the country he accepted the Parliamentary Labour Party's private verdict that he was no longer best placed to fight the next election ¹. He remains prime minister until Labour chooses a successor.

The Parliamentary Labour Party (PLP) is the body of Labour MPs at Westminster, and its confidence had been draining for weeks. Wes Streeting quit the Cabinet in May citing Starmer's inability to lead , eight junior ministers and aides walked out over two days , and the PLP split almost evenly, 96 against Starmer to 103 defending, when it last tested the question .

Starmer's decision to stay on as caretaker rather than trigger an immediate handover keeps a functioning government in place while the party runs its timetable. His resignation ends the leadership he won in 2020 and starts a succession that could be settled in under a month.

Deep Analysis

In plain English

Keir Starmer had been Labour leader and prime minister since 2024. On 22 June he resigned both roles, saying he accepted that his own MPs no longer believed he was the right person to lead Labour into the next general election. Unlike some other parties, Labour has no formal process for MPs to vote a sitting leader out. Instead, the pressure built through private conversations between Starmer and his MPs, and through a string of resignations and warning signs, including Labour holding the Makerfield by-election just four days earlier by a narrower margin than the government would want. Starmer remains prime minister in a caretaker capacity until Labour chooses a new leader, which is expected within weeks.

Deep Analysis

Root Causes

Labour's rulebook, unlike the Conservatives', has no statutory mechanism for MPs to force a sitting leader from office through a confidence vote; a leader can only be removed by resigning or by a full leadership contest being triggered against them.

That gap means pressure builds informally, through cabinet resignations, private PLP soundings and by-election results read as referendums on the leader, until the leader concludes unassisted that the parliamentary party will not back them into the next general election.

What could happen next?

Consequence
A prime ministerial resignation without a general election hands the succession decision to Labour's internal rules rather than to voters, at least until the next scheduled election.
Precedent
A leadership change resolved entirely through internal party process, with no confidence vote and no election, will be read as a test of whether the public accepts a change of prime minister they had no direct say in.

Primary parallel: Margaret Thatcher resigned in November 1990 after cabinet colleagues privately convinced her she could not win a second leadership ballot, the same soundings-first, resignation-before-defeat pattern now repeating with Starmer and the Parliamentary Labour Party.

Counter-parallel: Tony Blair's 2007 handover to Gordon Brown followed a publicly negotiated timetable announced well in advance, a far more orderly transition than Starmer's abrupt exit with no successor yet chosen and a leadership contest timetable still being drawn up.

Consensus view: The Institute for Government assesses the exit as unusually orderly for a sitting prime minister levered out mid-term, achieved through private soundings and cabinet resignations such as Wes Streeting's rather than any formal confidence vote, since Labour's constitution has no equivalent of the Conservative Party's 1922 Committee mechanism.

Counter-view: Compass, the Labour-left pressure group, argues that resolving a leadership crisis through private soundings rather than a public and recorded vote denies both party members and the country clarity about who actually forced the decision and on what evidence.

Key tension: Whether the absence of any codified mechanism for removing a sitting Labour prime minister makes this a clean voluntary resignation or an informally engineered removal dressed as one.

Different Perspectives

Ian Davidson, Acting Returning Officer for Clacton

Davidson's office printed a 90cm ballot paper for the record 34-candidate field, with nothing in electoral law capping candidate numbers or the £500 deposit each pays. He expects the paper's size to raise printing costs and slow the count into the early hours, a strain that follows from the major parties' boycott, not from turnout.

Scottish Labour members

Members now choose between Michael Marra and Joe Fagan after Monica Lennon fell one MP nomination short of the three-MP, three-MSP threshold, a bar set by MPs and union officials rather than the wider membership. Whoever wins takes office having faced only one rival on the members' ballot.

Labour Party

Labour gained Penistone East from Reform on 20 August but lost Harraby South to Reform the same night, a wash that undercuts any claim of momentum. The party can point to beating Reform in a genuinely fought contest, but not to a pattern running only in its favour.

Liberal Democrats

The Liberal Democrats took two of Reform's May wards, Almondbury on 13 August and St Neots Eynesbury on 20 August, the latter on a 29.8-point rise in their own vote share. Both results let the party claim it is the beneficiary when voters turn against Reform, not Labour or the Conservatives.

Reform UK

Reform UK can point to winning Clacton unopposed by the other major parties and to taking Harraby South from Labour, a ward it had never previously contested. That gives the party two results to cite even as three previously held wards changed hands elsewhere in August.

Sinn Féin

Sinn Féin's John O'Dowd ruled out a Stormont walkout on 11 August despite calling the DUP increasingly difficult to work with, closing a question Conor Murphy had left open a fortnight earlier. Only Sinn Féin or the DUP can collapse the joint First Minister office, so the denial gives up the party's own leverage in budget talks.
