LONDON (Reuters) - Sadiq Khan was re-elected London Mayor on Saturday as had been widely expected, providing some joy to the opposition Labour Party which has suffered a series of disappointing results in other local elections.

Khan, who became the first Muslim to head a major Western capital after his victory in 2016, saw off his main challenger, Shaun Bailey, the candidate from Prime Minister Boris Johnson's Conservative Party.
