Keir Starmer used a round of Sunday interviews to insist he is going nowhere, framing his battered government as "a ten-year project" and dismissing the suggestion that Thursday's local election results — the worst for a governing party in more than three decades — should end his tenure after less than a year.

His defiance has not settled the Labour benches. Catherine West, a former junior Foreign Office minister sacked in last year's reshuffle, has told colleagues she will collect signatures and trigger a leadership contest herself if no cabinet minister moves by Monday morning. She told the BBC she had been "inundated with support from MPs" and could "go all the way".

To force a contest under Labour's rules West would need 81 signatures — a fifth of the party's 403 MPs. She has so far publicly secured backing from around ten, but allies say her real aim is to provide a stalking horse: a vehicle to compel a more senior figure into the open. Several cabinet names — none of them yet declared — are being discussed in WhatsApp groups across the parliamentary party.

The catalyst was Thursday's vote, which produced losses on a scale Labour strategists had not modelled. The party shed roughly 1,200 council seats and ceded control of 37 councils, including a string of northern towns held continuously since the 1970s. Reform UK gained more than 1,400 seats and now controls councils in formerly safe Labour territory; the Greens advanced in cities, peeling off Labour's urban left.

Starmer told Sky News he had "not done enough" to address voters' concerns and would set out a "fresh direction" in a Monday morning speech. Education Secretary Bridget Phillipson, sent out across the morning slots, said the cabinet remained behind him and that the government would "reset" rather than retreat.

Reform UK leader Nigel Farage, in a column for the Sunday Telegraph, called the results "the end of the old establishment's two-party system" and said his party would now actively prepare for an early general election. The Reform leadership has spent the weekend on a tour of newly-won councils.

The Conservative response has been muted. Kemi Badenoch, who has spent months arguing that Labour's collapse should benefit her party, instead saw the Conservatives lose ground to Reform in seats they had hoped to win back. Her aides say she will not move against Starmer this week, on the grounds that a wounded prime minister suits the Tories better than a fresh one.

Polling published by More in Common on Sunday suggested only 17 per cent of voters now want Starmer to lead Labour into the next election. The same survey found Reform on 31 per cent of the national vote, ahead of Labour and the Conservatives, with the Greens close to double digits — a four-party landscape that would scramble any general-election projection.
