In a show of overwhelming support for the first Muslim head of a major Western capital, London Mayor Sadiq Khan has been re-elected for a second time, with a 55.2 per cent margin. 

The win is in stark contrast to fellow Labour Party candidates across the United Kingdom, who have seen a series of disappointing losses in other local elections. 

Experts are reporting his win is thanks to the large demographic of young, ethnically-diverse, and pro-European Union people in London.
