The electorates of Hackney, Lewisham, Newham and Tower Hamlets also elected their executive mayors, who operate in place of council leaders in those boroughs.

Ward changes took place in Hackney, Kensington and Chelsea, and Tower Hamlets, which reduced the total number of councillors by 10 to 1,851.

Following the elections, two of the thirty two London borough councils were in no overall control, a decrease of one.

Three seats in Barnet (Colindale) and three in Tower Hamlets (Blackwall and Cubitt Town) were vacancies until elections held on 26 June 2014 in Colindale[4] and on 3 July 2014 in Blackwall and Cubitt Town.
