Chancellor Rishi Sunak’s Conservative Party is widely expected to be defeated by the main opposition, centre-left Labour Party, after 14 years in power under five prime ministers.
Under Britain’s “single-member constituency” system, the Conservative and Labour parties have traditionally dominated British politics, making it difficult for smaller parties to win seats in Parliament.

Sunak, 44, took office in October 2022, taking over a Conservative party and economy in shambles after Liz Truss’s short-lived premiership. The Oxford University graduate and former Goldman Sachs hedge fund manager is Britain’s first person of colour to lead the country and the first Hindu to become prime minister. Sunak touts himself as the man who has brought stability to the government, but critics say he lacks political acumen and is out of touch with ordinary voters.

What do they promise? Strengthen the economy and cut taxes by around £17 billion a year. Increase public health spending above the rate of inflation and increase defence spending to 2.5% of GDP by 2030. The party says it will pay for this by cutting tax evasion and reducing welfare spending. They also promise to cap immigration and exclude some asylum seekers from Rwanda.
Labor
Who is their leader? Keir Starmer.
Starmer, a 61-year-old lawyer and former attorney general for England and Wales, is currently the front-runner to become Britain’s next leader. A centrist and pragmatic man, he has worked to defuse divisions within the party and distance it from the more explicitly socialist policies of former leader Jeremy Corbyn. He has been described as uninspiring and unambitious, but under his leadership, Labour’s popularity has soared.

What are they promising? Drive “wealth creation” under a 10-year infrastructure strategy, encouraging investment and improving Britain’s infrastructure such as rail; Create a national clean electricity company to boost energy security, funded by a temporary levy on oil and gas giants; Tax private schools to cover the costs of thousands of new teachers in state schools; Reduce public health waiting times, which are at record highs.
LDP
Who is their leader? Ed Davey.
Davie, 58, was first elected to Parliament in 1997. A former economic researcher, he served as the government’s energy and climate change minister during the shaky Conservative-Liberal Democrat coalition government from 2012 to 2015. Davie, who became leader of the centre-left Liberal Democrat party in 2019, was little known before making headlines for a number of eccentric stunts during this election, including a bungee jump to encourage voters to “take a leap of faith”.

What are they promising? Fixing Britain’s overburdened health and social care system, including free home care; investing in renewable energy and home insulation; cracking down on wastewater treatment companies; lowering the voting age to 16; and rejoining the European Union’s single market.
Reform UK
Who is their leader? Nigel Farage.
Farage, a political firebrand who prides himself on being a disruptor of British politics, has been a serious headache for the Conservative Party since he announced his candidacy. The 60-year-old populist has long polarized public opinion with his anti-immigration rhetoric and Eurosceptic stance. A key promoter of Brexit, Farage has charmed many disillusioned Conservative voters with his promises to cut immigration and focus on “British values.” Farage has run for parliament seven times but has never won.
How many seats did the party win in the last election? Zero, although this year the party won its first MP after former Conservative deputy chairman Lee Anderson moved to the Reform Party.
What are they promising? Freezing all “non-essential immigration” and banning international students from bringing dependents with them. Withdrawing from the European Convention on Human Rights so asylum seekers can be deported without the intervention of a human rights court. Scrapping “net zero” targets to reduce greenhouse gas emissions in order to lower energy bills.
Scottish National Party (SNP)
Who is their leader? John Swinney.
Mr Swinney, 60, became the SNP’s third leader in just over a year in May. He has sought to bring stability to a party in turmoil since the abrupt resignation of Scotland’s longtime first minister, Nicola Sturgeon, last year amid a campaign finance investigation and the eventual criminal charges against her husband. Mr Swinney is a long-time member of the party, having joined at age 15 and served as leader from 2000 to 2004.

He wants to rejoin the European Union and the European single market. He has also called for an increase in the public health budget, an end to the UK’s Scottish-based nuclear deterrent, and an immediate ceasefire in Gaza.
Green Party
Who are their leaders? Cara Deniel and Adrienne Ramsay.
Denier, a mechanical engineer, worked in the wind energy sector before joining the Green Party in 2011. The 38-year-old served as a local councillor in Bristol, a city in southwest England, for nine years. In 2021, he was elected co-leader of the Green Party alongside Ramsay, a local government politician with a history of working for environmental charities.
