The Assembly acts as the eyes and ears of Londoners at City Hall. Assembly Members hold the Mayor to account by examining Mayoral strategies, decisions and actions to make sure they are in the public interest. They investigate issues of importance to Londoners.

The Mayor makes decisions that affect Londoners' lives. This includes decisions about policing, transport, housing, fire and emergency planning, the environment, culture, economic development, regeneration, planning and development, and tackling health inequalities.  

The position of Mayor of London was created in 2000 to be the elected voice of the capital and champion London both at home and abroad.

Votes for the Mayor of London, London Assembly Constituency member and London Assembly London-wide member contests will be verified and counted over the two days after polling day on Thursday 2 May.

The verification of ballot papers from all three contests will take place on Friday 3 May, and the votes cast for all three contests will be counted on Saturday 4 May.

Votes at previous GLA elections have been counted electronically at three count centres. In 2024, votes will be counted by hand at 14 Assembly Constituency count venues across London.  

The Mayoral and London-wide results will  be declared on Saturday 4 May at City Hall. The 14 constituency results will be declared at the constituency venues.

Verification is the process of checking that the number of ballot papers delivered to the count is the same as the number issued at polling stations and by post.

Following verification we will know how many ballot papers each constituency has to count and the turnout for each contest.

The Mayor of London is elected by the ‘first past the post’ system. This means the candidate with the most votes is elected as Mayor of London.

The 14 London Assembly Constituency Members are elected using the ‘first past the post system’.

This means the candidate in each constituency with the most votes is elected as a London Assembly (constituency) Member. 

The 11 Assembly London-wide Members are elected using a form of ‘proportional representation’ - this system is used to ensure the overall Assembly reflects how London voted.

Seats are allocated according to the ‘modified d’Hondt formula’. This takes into account how many Constituency London Assembly Member seats a party or candidate has already won, and allocates the remaining seats to ensure the overall make-up of the Assembly is proportionate to how Londoners have cast their votes.

These results are announced last as the Assembly seats cannot be allocated until the constituency results have been announced.

Seats won by parties are allocated to party candidates in the order they appeared on the relevant party’s list of candidates.

The formula uses 11 rounds of calculations to allocate the 11 London-wide seats.

It divides the number of London-wide Assembly votes for each party or candidate by the number of Constituency Assembly Member seats already won, plus one.

From the second round onwards, the number of London-wide Assembly Member seats won by parties up to that point is added to the number of Constituency Assembly Member seats it won.

At each of the 11 rounds, the party with the highest calculated total is assigned a London-wide Assembly Member.

This ensures that that the overall make-up of the Assembly is proportionate to how Londoners have cast their votes in the London-wide Assembly contest.

See the results for 2021.

The new Mayor and Assembly members take office on the second day after the results are declared with a term of 4 years.  

The next Mayor of London and London Assembly elections are in May 2028.

The next Mayor of London election will be in May 2028.
