 Boundary changes coincided with a shrinking of the council, so all seats were up for election.In each ward, 3 candidates were elected, with the leading candidate being elected for 4 years, the second-placed candidate being elected for 3 years and the third-placed candidate being elected for 2 years.As a result, there will be no borough elections in 2017, but a third of the council will be up for re-election in each of 2018, 2019 and 2020.
