List of Prime Ministers of UK: Here’s the Full List of UK Prime Ministers
Tony Blair (1997–2007)
A former barrister who modernized the Labour Party by moving it to the political center under the brand “New Labour.”
The key domestic success is that it established the National Minimum Wage, significantly expanded spending on the National Health Service (NHS), and introduced constitutional devolution, creating the Scottish Parliament and Welsh Assembly.
However, public and party opposition mounted heavily over his staunch support of the 2003 Iraq War alongside the United States. Facing a collapsing domestic approval rating and internal party pressure, he handed over power to his long-time political partner and Chancellor, Gordon Brown.
Gordon Brown (2007–2010)
The longest-serving Chancellor of the Exchequer in modern times, known for his formidable command over domestic economic policy.
The key domestic success was that it committed significant public funding to bail out failing financial institutions and pushed international leaders at the 2009 London G20 Summit to inject global liquidity into the economy, preventing a total economic collapse.
However, heavily damaged by the voter backlash over the recession, Labour lost its majority in the 2010 general election. After coalition negotiations between Labour and the Liberal Democrats fell through, Brown resigned to allow a new government to form.
David Cameron (2010–2016)
A PR-savvy politician who rebranded the Conservative Party as socially compassionate and modern, legalizing same-sex marriage in 2013.
The key domestic success was that it formed a historic coalition government with the Liberal Democrats and implemented an aggressive austerity programme to drive down the national deficit.
However, to manage anti-EU rebels within his own party, Cameron gambled by promising the 2016 Brexit Referendum. Believing the UK would choose to stay, he spearheaded the “Remain” campaign. When the country voted 52% to leave, his authority was shattered, prompting his resignation the next morning.
Theresa May (2016–2019)
A long-serving Home Secretary who took office on a platform of delivering a structured and orderly departure from the European Union.
The key domestic success was that it created the Department for International Trade and legally committed the UK to a target of net-zero greenhouse gas emissions by 2050.
However, intending to strengthen her mandate, she called a snap election in 2017 but instead lost her parliamentary majority, forcing her into a fragile minority government. Paralyzed by a deeply divided Parliament, her negotiated Brexit withdrawal agreement was rejected three times, forcing her to step down in tears.
Boris Johnson (2019–2022)
The highly charismatic former Mayor of London who effectively utilized populist messaging to break the parliamentary Brexit deadlock.
The key domestic success was that it secured a massive 80-seat majority in December 2019, successfully signed the UK–EU Trade and Cooperation Agreement, and rolled out the COVID-19 vaccine program.
However, his administration became mired in a continuous loop of ethical scandals. The final blow was “Partygate”, the revelation of illegal social gatherings held at 10 Downing Street during strict nationwide COVID lockdowns. Following a wave of mass resignations from his own cabinet, he lost the confidence of his party and resigned.
Liz Truss (2022)
A free-market libertarian who campaigned on an aggressively deregulatory platform to kickstart economic growth.
The key domestic success was that it implemented a brief nationwide energy price guarantee to shield households from surging winter utility bills.
However, her Chancellor unveiled an unbudgeted “mini-budget” consisting of £45 billion in tax cuts. The plan completely terrified global financial markets, sending the British pound crashing against the dollar and forcing the Bank of England to stage an emergency intervention to rescue pension funds. She resigned after a chaotic 49 days in office.
Rishi Sunak (2022–2024)
A former hedge fund manager who rose to prominence as Chancellor by steering the economic furlough scheme during the pandemic.
The key domestic successes were that it stabilized the financial markets post-Truss, signed the Windsor Framework to resolve the complex Northern Ireland post-Brexit trade disputes, and successfully halved inflation.
However, struggling to cut public health waiting lists and manage legal immigration targets, Sunak called an early summer election. The electorate severely punished the Conservatives for a decade of instability, resulting in the worst electoral defeat in the party’s modern history.
Sir Keir Starmer (2024–2026)
A former Director of Public Prosecutions (DPP) who comprehensively purged the Labour Party of its far-left factions to rebuild its economic credibility.
The key domestic success was that it delivered the fastest fall in NHS waiting lists in 17 years, passed sweeping legislative overhauls to strengthen workers’ and renters’ rights, and created a state-owned green energy entity.
However, despite a historic landslide victory, Starmer faced a stubbornly sluggish economy. A string of early policy walkbacks combined with catastrophic results in the Spring 2026 local elections across England, Scotland, and Wales completely destabilized his position. Confronted with intense internal party pressure and a severe cabinet split, he announced his resignation after less than two years in office.
Andy Burnham (2026–Present)
Affectionately dubbed the “King of the North,” Burnham built a national profile as the high-visibility Mayor of Greater Manchester after serving as an MP and Health Secretary under Gordon Brown.
He won the Labour leadership contest unopposed. Stepping outside of No. 10, he immediately promised to “rewire Britain” by decentralizing sweeping powers away from Westminster to local regions, fixing the acute cost-of-living crisis, and restoring trust in a highly fractured political system.
