Who is Labour’s Keir Starmer, the doubtless new chief of Britain?

LONDON — Britain looks likely to elect its first Labour prime minister in 14 years, with an expected landslide victory for the opposition party during the July 4 elections.

Keir Starmer would take the country’s top job from Rishi Sunak with exit polls suggesting his left-of-center party could have a majority of around 170 seats.

Starmer, 61, has had a rapid political ascent after entering U.K. parliament less than a decade ago. But many Britons still know little about the man who has positioned himself as the country’s change candidate.

CNBC takes a look at the U.K.’s new prime minister and his platform.

Starmer also served as a human rights adviser during former Labour Prime Minister Tony Blair’s landmark Northern Ireland Good Friday Agreement.

In 2008, a year after marrying his wife, Victoria, Starmer became director of public prosecutions, putting him at the head of the U.K.’s Crown Prosecution Service.

Starmer was knighted in 2014 for his services to criminal justice and was elected to Parliament the following year, serving as immigration minister and Brexit minister for the opposition.

In 2020, he was appointed Labour leader and instigated a major overhaul of the party after the resignation of Jeremy Corbyn, who led the faction to record loss in the 2019 election.

In his 2024 election campaign, Starmer touted a “decade of national renewal” for the country following what Labour has described as years of spending cuts and falling living standards under the Tories.

In the party’s election manifesto, published last month, Starmer outlined spending measures to create a new publicly owned energy company, reduce NHS waiting times, build new homes and renationalize rail services.

But he also positioned himself as staunchly pro-business, continuing his years-long charm offensive on traditionally right-leaning voters with plans for “wealth creation” and a National Wealth Fund.

“Economic growth and social justice must go hand in hand,” Starmer said at the launch event of the manifesto.

Labour has outlined five long-term missions if it comes to power: drive economic growth, invest in green energy, overhaul the NHS, create safer streets, and deliver “opportunity” through a new skills agenda. To aid these goals, Starmer is planning a radical shake-up of government ministries, Labour officials told the FT.

Starmer, who voted for the Remain campaign not the depart the EU in the U.K.’s 2016 EU referendum, has also pledged to improve the “botched” U.K.-EU deal, including in areas such as trade, research and security. However, he has insisted there is no case for Britain to rejoin the bloc.

Despite his change agenda, Starmer is seen by many as an establishment figure, lacking the charisma of other politicians. A YouGov poll from earlier this year ranked him behind Reform’s Nigel Farage in terms of public popularity — and his rating fell further among younger voters.

Critics have also questioned Starmer’s core values — for example, remaining in Corbyn’s top team even as the party leader faced accusations of antisemitism within Labour. Starmer later suspended Corbyn from the party. Others have accused him of betraying the left by courting business leaders and dropping pledges such as abolishing university fees.

After a bumpy few years for British politics, though — with three different Conservative prime ministers in 2022 alone — Starmer’s supporters are championing him as a neutral figure of stability after a period of significant political upheaval.
