How are London Assembly (London-wide) Member results calculated?
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. This means that these Assembly seats cannot be allocated until the constituency results have been announced.
The 11 seats are allocated using a mathematical formula – the ‘Modified d’Hondt Formula’. The formula uses the votes cast in the London Assembly (London-wide) Member contest and takes account of the number of London Assembly (constituency) Member seats that each political party has already won.
11 rounds of calculations then take place to fill the 11 vacant Assembly Member seats, with the party or independent candidate with the highest result at each round being allocated the seat. Seats won by parties are allocated to party candidates in the order they appeared on the relevant party’s list of candidates.
