Sir James Cleverly has announced his candidacy for the London mayoralty in the 2028 election, setting the stage for a competitive contest against incumbent Mayor Sir Sadiq Khan. The former foreign secretary, home secretary, education secretary, and Conservative Party chairman brings extensive political experience to the race, marking the first time in a decade that Khan will face a high-profile opponent from the Conservative Party.

Cleverly’s decision to run comes after years of speculation. Initially considered a potential candidate for the 2024 mayoral race, he deferred his ambitions to focus on his duties as home secretary, particularly amid efforts to address challenges within the UK’s immigration system. With his wife now in recovery following an illness, Cleverly has renewed his campaign efforts, indicating a strategic move by the Conservatives to reclaim London’s mayoralty for the first time since Boris Johnson’s tenure ended in 2016.

The London mayoral election is scheduled for May 2028, a timing that adds to its political significance. London has traditionally leaned towards Labour in local elections, but Johnson's win in 2008 demonstrated that a well-positioned Conservative candidate with broad appeal can succeed. The upcoming contest will not only test Khan’s hold on the office should he seek a fourth term but also gauge Labour’s ability to sustain voter support under current or future leadership.

The election is also viewed as a barometer for national political trends ahead of the next general election. Conservative MP Kemi Badenoch’s efforts to rebrand the party nationally may be reflected in how Cleverly performs in the capital, while the fate of parties like Reform UK and its candidate Laila Cunningham will also become clearer. Cunningham, a former prosecutor, has recently drawn attention for her unconventional media appearances, but polling indicates she holds a presence in London’s political landscape.

Cleverly’s candidacy addresses past criticisms of the Conservatives’ previous mayoral efforts. His background includes a term as deputy mayor of London, and his profile contrasts with that of Susan Hall, who ran in 2021 with limited party support yet managed to secure 32 percent of the vote, outperforming national Conservative polling. Analysts suggest that Cleverly’s combination of political gravitas, communication skills, and deeper party backing could pose a formidable challenge to Khan.

With Labour having undergone leadership changes, including the replacement of former leader Sir Keir Starmer, and the broader political environment evolving, the 2028 mayoral election promises to be a key contest for both the Conservative and Labour parties. It offers an early indication of voter sentiment in the capital and potentially foreshadows broader national electoral dynamics in the years to follow.
