The number of local councillors in Doncaster is to be reviewed.
The Local Government Boundary Commission for England has been asked to establish whether the size of the council is appropriate. It will begin its work in April and draft recommendations are expected to be published in 2014.
It will meet with the full Council, the Mayor, the Group Leaders, parishes and officers.
Peter Davies, the Mayor or Doncaster, said he was "delighted to welcome the Commission".
