London's Labour mayor Sadiq Khan won a third term in office on Saturday, dealing the Conservatives another defeat in local elections.
Khan, the first Muslim mayor of a Western capital, was widely expected to win due to Labour's surge nationally and the Conservatives' poor polling.
He increased his margin of victory compared to the last election.
The results were dismal for Prime Minister Rishi Sunak and his Tories, who finished third in local council tallies and lost nearly 500 seats across England.
In the recent mayoral elections, Labour made significant gains, causing Conservative losses in Manchester, Liverpool, Yorkshire, and the capital, among other places.
The results in the West Midlands were too close to call, and an unexpected Tory defeat there could leave Sunak with only one notable success: the mayor's third term in Tees Valley, northeast England.
Sunak acknowledged voter frustration but maintained that Labour was not winning in crucial areas for a majority.
Meanwhile, Labour seized a parliamentary seat from the Conservatives.
The Labour Party, led by Keir Starmer, won the Blackpool South constituency and the East Midlands mayoral race, and is calling for a national general election.
Sunak has not yet announced a date but is planning for a poll in the second half of 2024.
Labour has enjoyed double-digit poll leads during Sunak's 18 months in office due to previous Tory scandals, cost-of-living crisis, and other issues.
They are currently defending over 1,000 council seats, many of which were secured in 2021 when they led in national polls before
Johnson's and Truss's tenures.
In the local elections held over the weekend, the Labour Party lost nearly half of their seats and finished third behind the Liberal Democrats.
According to projections by BBC and Sky News, Labour would win 34% of the votes in a nationwide contest, with the Conservatives trailing by nine points.
The Conservatives suffered 11 by-election losses during this parliament, the most for any government since the late 1960s.
Despite speculation of a leadership challenge, there has been no sign of restive Tory lawmakers attempting to replace the current prime minister.
Labour suffered losses in local elections, losing control of one authority and experiencing councillor defeats to independents.
Analysts attributed these losses to Labour's stance on the Israel-Hamas war.
Polling expert John Curtice expressed concern, stating that the desire to defeat the Conservatives outweighed support for Labour.
Sir Keir Starmer's position as Labour's heir to Tony Blair remains uncertain.
