The Mexborough First political party has announced three candidates will stand for election in May.
Serving councillor Andy Pickering will stand for re-election, while Sean Gibbons and Bev Chapman will contest the other two seats.
Coun Pickering said: “I have been privileged to have been given the opportunity to speak up for the town, and promise if anyone tries to damage our town or hide the truth, I will, and Mexborough First will expose it.”
Mr Gibbons, aged 40, who runs foodbanks across Doncaster, added: “Many people know that I ‘say it how it is’ and constantly badger Doncaster Council for better services for Mexborough. As a councillor, I would not stop doing this.”
Ms Chapman, a market trader, said: “I have been chosen as a candidate to represent you, the people of Mexborough.
“I would appreciate the chance to put you and your issues to the top of the council’s agenda.”
The other two serving ward members in Mexborough are Labour councillors Sue Phillips and Tracey Leyland-Jepson.
All seats on Doncaster Council are up for election this year due to ward boundary changes.
