All London borough council seats were up for election. Both major parties lost votes to the SDP-Liberal Alliance, but whilst the Conservatives gained 20 council seats, Labour lost 101.
The party's result of 30.4%, 12 councils and 781 councillors was the worst Labour result since 1968.
The previous Borough elections in London were in 1978.[1]
To date, this remains the last London local election in which the Conservatives won a majority of council seats or councils, as well as the last time the party won over 40% of the vote. The Conservatives would not win the popular vote in a London local election for another two decades, and would not win a plurality of seats in London again until the election of 2006, 24 years later.
