Labour Party leader Keir Starmer has officially become the new prime minister of the United Kingdom after he led his party to achieve a landslide victory in Britain’s general election, unseating the incumbent Conservatives after 14 years.

Early on Friday morning, Labour passed the threshold needed to govern alone as outgoing PM Rishi Sunak conceded defeat.
Starmer officially became the new prime minister after meeting King Charles III at Buckingham Palace in London.

He said he would lead a “government of service” on a mission of national renewal in his first official remarks on Friday.
Starmer acknowledged in his first speech outside 10 Downing St that many people are disillusioned and cynical about politics, but said his government would try to restore faith in government.
“My government will make you believe again,” Starmer said as supporters cheered him on outside 10 Downing St.

“The work for change begins immediately,” he said. “We will rebuild Britain. …. Brick by brick we will rebuild the infrastructure of opportunity.”
In the merciless choreography of British politics, Starmer took over the official residence about two hours after Conservative leader Rishi Sunak and his family left the home and the king accepted the Conservative leader’s resignation.

Labour’s triumph and challenges
With almost all the results in, Labour had won 410 seats in the 650-seat House of Commons and the Conservatives 118.
For Starmer, it’s a massive triumph that will bring huge challenges, as he faces a weary electorate impatient for change against a gloomy backdrop of economic malaise, mounting distrust in institutions and a fraying social fabric.

“Nothing has gone well in the last 14 years,” said London voter James Erskine, who was optimistic for change in the hours before polls closed. “I just see this as the potential for a seismic shift, and that’s what I’m hoping for.”

And that’s what Starmer promised, saying “change begins now.”
Anand Menon, professor of European Politics and Foreign Affairs at King’s College London, said British voters were about to see a marked change in political atmosphere from the tumultuous “politics as pantomime” of the last few years.

“I think we’re going to have to get used again to relatively stable government, with ministers staying in power for quite a long time, and with government being able to think beyond the very short term to medium-term objectives,” he said.

Britain has experienced a run of turbulent years — some of it of the Conservatives’ own making and some of it not — that has left many voters pessimistic about their country’s future. The U.K. divorce from the European Union followed by the COVID-19 pandemic and Russia’s invasion of Ukraine battered the economy, while lockdown-breaching parties held by then-Prime Minister Boris Johnson and his staff caused widespread anger.

Johnson’s successor, Liz Truss, rocked the economy further with a package of drastic tax cuts and lasted just 49 days in office. Truss, who lost her seat to Labour, was one of a slew of senior Tories kicked out in a stark electoral reckoning.

While the result appears to buck recent rightward electoral shifts in Europe, including in France and Italy, many of those same populist undercurrents flow in Britain. Reform UK leader Nigel Farage roiled the race with his party’s anti-immigrant “take our country back” sentiment and undercut support for the Conservatives and even grabbed some voters from Labour.
Conservative vote collapses as smaller parties surge

The result is a catastrophe for the Conservatives as voters punished them for 14 years of presiding over austerity, Brexit, a pandemic, political scandals and internecine conflict.
The historic defeat — the smallest number of seats in the party’s two-century history — leaves it depleted and in disarray and will spark an immediate contest to replace Sunak, who said he would step down as leader.

In a sign of the volatile public mood and anger at the system, the incoming Parliament will be more fractured and ideologically diverse than any for years. Smaller parties picked up millions of votes, including the centrist Liberal Democrats and Farage’s Reform UK. It won four seats, including one for Farage in the seaside town of Clacton-on-Sea, securing a place in Parliament on his eighth attempt.
The Liberal Democrats won about 70 seats, on a slightly lower share of the vote than Reform because its votes were more efficiently distributed. In Britain’s first-past-the-post system, the candidate with the most votes in each constituency wins.

The Green Party won four seats, up from just one before the election.
One of the biggest losers was the Scottish National Party, which held most of Scotland’s 57 seats before the election but looked set to lose all but handful, mostly to Labour.
Labour was cautious but reliable

Labour did not set pulses racing with its pledges to get the sluggish economy growing, invest in infrastructure and make Britain a “clean energy superpower.” But the party’s cautious, safety-first campaign delivered the desired result. The party won the support of large chunks of the business community and endorsements from traditionally conservative newspapers, including the Rupert Murdoch-owned Sun tabloid, which praised Starmer for “dragging his party back to the center ground of British politics.”
