The 1966 Sheffield City Council elections were held in May, with one third of the council up for election and double vacancies in five wards - Cathedral, Ecclesall, Manor, Tinsley and Woodseats. There were no changes in seats, with overall turnout slumping to a low of 22.5% being the main story of the night.[1]
The result had the following consequences for the total number of seats on the Council after the elections:
