Conservative Elections for the City of Westminster London borough were held on 6 May 2010.
The Conservatives retained control of the council, and all wards continued with the same party representation as at the previous borough election in 2006.
Labour won back the Church Street seat they had lost to the Conservatives at a 2008 by-election.
The percentage of vote share and majority are based on the average for each party's votes in each ward.
The raw majority number is the margin of votes between the lowest-placed winning party candidate and the opposition party's highest-placed losing candidate.
