The 2011 Southampton Council election took place on 6 May 2011 to elect members of Southampton Unitary Council in Hampshire, England. One third of the council (16 seats) was up for election. Labour won a majority of the seats being contested and the Conservatives stayed in overall control of the council.[1]
Southampton Council is elected in thirds, which means the vote share change is compared to the corresponding 2007 Southampton Council election.
Of the 16 Council seats up for election, Labour won 10 (up from 7 in 2010) the Conservatives won 6 (no change from 2010) and the Liberal Democrats won 0 (down from 3 in 2010).
