How the mayor is elected: Voters select their 1st and 2nd choices on the ballot. If no-one receives a majority, all candidates are dropped except the top two and the second-choices are counted.
One position to be elected in your area, to join 14 similarly elected citywide.
How the Constituency Member is elected: The candidate with the most votes, wins, whether or not they have a majority.
11 positions to be elected from party lists, citywide.
How the London-wide Member is elected: Votes from across London for this position are pooled. The 11 seats are then allocated based upon a mathematical formula – the Modified d’Hondt Formula. This takes into account the total votes cast in this ballot PLUS the number of Constituency London Assembly Member seats (above) that each political party has already won. 11 rounds of calculations take place to fill the 11 vacant Assembly Member seats, and the party or independent candidate with the highest result at each round is allocated the seat. Seats won by parties are allocated to party candidates in the order they appear on the relevant party’s list of candidates.
