Boris Johnson has created six deputy mayors with at least one more in the pipeline as he continues a reshuffle of key City Hall advisers.
London Assembly member James Cleverly is appointed chairman of London's fire authority, replacing controversial fellow Tory Brian Coleman who lost his seat.
Victoria Borwick, another Conservative on the Assembly, becomes the mayor's "statutory" deputy, in place of Richard Barnes, who was also an election night casualty for the Tories.
Isabel Dedring, the Deputy Mayor for Transport will retain her post.
Other deputy mayors include Kit Malthouse who moves from Policing to Business and Enterprise, Sir Eddie Lister who remains Deputy Mayor for Planning and Munira Mirza, Deputy Mayor for Education and Culture.
Former Hammersmith and Fulham council leader Stephen Greenhalgh is expected to become Deputy Mayor for Policing.
Ken Livingstone has been handing out a 'voucher' promising Londoners £1,000 off their tube, bus and rail fares if he wins the mayoral election.
Labour's candidate was on the campaign trail in Uxbridge, where he launched his transport manifesto.
He is promising that the average person will save £1,000 over the next four years under his leadership.
Mr Livingstone said: " I am saying to Londoners – keep hold of this voucher so that you have physical evidence of my promise to cut your fares. The voucher will be available online from today, but will only be valid if I am elected as Mayor on 3 May."
