in 2016 london elected its first blank mayor
London mayoral election, 2016 This was the first election to not feature either of the two previous holders of the office, Ken Livingstone and Boris Johnson, who had run against each other in 2008 and 2012. Johnson, as incumbent mayor, had chosen not to stand for re-election for a third term in office, having been elected as the Conservative Party MP for Uxbridge and South Ruislip at the 2015 general election. The campaign was dominated by the personal battle between Goldsmith and Khan, and their contrasting class and ethnic backgrounds.[2] Through his victory, Khan became the second Labour Party Mayor of London after Livingstone, and the first Muslim mayor of a European Union capital city.[3]
Age of candidacy In the UK (other than in Scotland) a person must be aged 18 or over (16 in Scotland) to stand in elections to all parliaments, assemblies, and councils at the European, UK, devolved, or local level. This age requirement also applies in elections to any individual elective public office; the main example is that of an elected mayor, whether of London or a local authority. There are no higher age requirements for particular positions in public office. Candidates are required to be aged 18 on both the day of nomination and the day of the poll. This was reduced from 21 by the Electoral Administration Act 2006.
