London mayoral contenders are beginning to campaign ahead of the 2028 election, aiming to challenge incumbent Sadiq Khan. Several political figures and parties are positioning themselves for what is widely seen as Khan’s most serious test yet, as campaigning starts before Khan has confirmed whether he will seek another term.

The Guardian reports that candidates from the Conservatives and Reform are trying to close space for Labour by attracting voters willing to shift to the right. The outlet describes an early push involving door-to-door campaigning and local organisation. Other coverage from Yahoo UK News also frames the election as an opportunity for rivals to make inroads before a final candidate list is settled.

A key uncertainty across reporting is Khan’s status as a candidate. He has not ruled out a further bid but has indicated he will decide next year, leaving opponents to prepare while his political intentions remain undecided.
