Leader - Bob Neill, assembly member for Bexley and Bromley
Group whip - Bob Blackman (assembly member for Brent and Harrow)
Group spokesmanships will be announced at a later date.
Bob Neill said: 'I am delighted to have been elected as Leader of the London Assembly Conservatives. As clearly the largest party in the assembly our principle objective is to use every means at our disposal to hold the mayor rigorously to account and to vigorously oppose those policies of his which we believe will damage Londoners.
'We are open to work constructively with any other Assembly members who share that aim.'
