Doncaster Metropolitan Borough Council is the local authority for Doncaster in South Yorkshire, England. The council is elected every four years. Since 2002 the council has been led by a directly elected mayor.
From 1973 to 2014, the council was elected by thirds every year except the year in which county council elections took place in other parts of England. In 2015, the whole council was elected due to boundary changes to the wards and it was decided that the whole council would be elected every four years in future from 2017, so that the council elections would coincide with the election of the Mayor of Doncaster in future.[1]
