Khan, who was first elected in 2016, has served longer than previous mayors Ken Livingstone and Boris Johnson. He expressed enthusiasm for the role, stating he "loves the job" and has "plenty of fuel in the tank" with many ideas.

The uncertainty surrounding Khan's future has led to speculation within the Labour party, with several MPs reportedly considering a run for the mayoral candidacy if he steps down. Other major parties are already preparing their candidates for the 2028 election.

James Cleverly is considered the likely Conservative candidate, Sarah Olney is expected to win the Liberal Democrat nomination, and Reform has already selected Laila Cunningham. Labour members have expressed concern that the delay in Khan's decision could hinder the party's preparations and ability to promote a new candidate.

Prime Minister Rishi Sunak has stated he supports Khan's decision, whatever it may be. Khan, who was recently ennobled as Lord Khan, has emphasized his commitment to doing what is best for London.
