However, a close colleague sought to quash the rumours over the weekend. Howard Wolfson, a former deputy mayor of New York, tweeted on Saturday:
Yesterday, Conservative sources played down the story, too, which first appeared in the Sunday Times. They insist the party is focusing totally on next month’s General Election.
Bloomberg may be reticent, but others have put themselves forward. For the Tories, businessman Ivan Massow has said he wants to stand, as has one of the current deputy mayors, Stephen Greenhalgh. Sol Campbell, the former footballer, has also publicly expressed an interest in running for the Conservatives.
Meanwhile, Labour’s big hitters are gaining momentum already, with former minister David Lammy already officially declared. Dame Tessa Jowell and current shadow London minister Sadiq Khan are also lining up bids.
For the Liberal Democrats, London Assembly member Caroline Pidgeon is the clear frontrunner, although she has not yet made her intentions for 2016 public.
