Rotherham Metropolitan Borough Council is the local authority for Rotherham in South Yorkshire, England. The council is elected every four years. Since the last boundary changes in 2004, 63 councillors have been elected from 21 wards.
As part of the government's response to the Rotherham sexual abuses scandal, the Secretary of State for Communities and Local Government, Eric Pickles made an order under the Local Government Act 2000 to switch Rotherham council to holding all-out elections in 2016 and then every fourth year after (the boundaries were not changed). Until then, Rotherham was elected 'in thirds' like other Metropolitan Boroughs, with a third of the council being elected in 3 years out of every 4-year cycle.
The 50% vote increase for the Liberal Democrats marked the highest ever swing in their favour since the creation of the council.
