Will Sadiq Khan win the 2028 London mayoral election?

The provided articles do not contain any information about the 2028 London mayoral election, Sadiq Khan's candidacy, his opponents, or any polling data. Article BBC article discusses a charity boxing challenge, which is unrelated to electoral prospects. Article Guardian article is an opinion piece by Sadiq Khan about the Ulez policy, which does not address his re-election chances. Without any relevant evidence about the election, the probability of him winning cannot be assessed beyond a baseline. Given the lack of information, I assign a probability of 0.5, reflecting uncertainty rather than a confident prediction.
