The London Assembly

The London Assemblyis a 25-member elected body, part of the Greater London Authority, that scrutinises the activities of the Mayor of London and has the power, with a two-thirds supermajority, to amend the Mayor's annual budget and to reject the Mayor's draft statutory strategies.

The London Assembly was established in 2000. It is also able to investigate other issues of importance to Londoners (most notably transport or environmental matters), publish its findings and recommendations, and make proposals to the Mayor.

The Assembly comprises 25 members elected using the additional-member system of mixed-member proportional representation, with 13 seats needed for a majority. Elections take place every four years, at the same time as those for the mayor of London. There are 14 geographical constituencies, each electing one member, with a further 11 members elected from a party list to make the total number of Assembly members from each party proportional to the votes cast for that party across the whole of London using a modified D'Hondt allocation.

A party must win at least 5% of the party list vote in order to win any seats. Members of the London Assembly have the post-nominal title "AM". The annual salary for a London Assembly member is approximately £60,416.
