The Labour Party retained control of the council, which it had held continuously since 1973.

In the previous result the changes were that Labour party candidates gained two Conservative-held seats and a Liberal Democrat took a Labour councillor-held seat.

This election saw three seats in that group convert to the now largest formal opposition group of councillors, local Conservatives.
