On May 6, Londoners will elect a mayor, whose performance will help determine whether this is the start of a period of decline for Europe's biggest city — or a chance to do things better. Current Mayor Sadiq Khan, who is favored to win re-election, says his top priority is preserving jobs threatened by the economic blow of the pandemic.
