Electing the Mayor and Assembly

The London Elects website has lots of information about the elections.
Organising and overseeing the elections
There are three different ‘contests’ that make up GLA elections – and three different ballot papers for voters. These are for:
- the Mayor of London
- the 14 Members of the London Assembly that represent London’s 14 Constituencies
- the 11 Assembly Members that represent the whole of London (London-wide Members)
The Greater London Returning Officer (GLRO) is responsible for overseeing the three contests, including the preparations for the poll and the counting of the votes. The GLRO is appointed by the Mayor but acts and takes decisions independently of the GLA – and is ultimately responsible to the courts. The GLRO is also the Chief Officer of the GLA - Mary Harpley.
The GLRO is supported by the London Elects team, based at and made up of staff from City Hall. London Elects works closely with a number of partners to deliver the elections, most importantly London’s boroughs and the 14 Constituency Returning Officers.
