Land-league campaigner Gerry O’Boyle is to contest the local elections in the Roscommon Municipal District.
He unsuccessfully stood in the 2014 Roscommon-South Leitrim by-election and the 2016 general election in Mayo.
Mr O’Boyle lives at Ballinlough but is from Ballyhaunis.
Meanwhile, Cootehall road-safety campaigner Noel McTiernan is still considering whether to put his name forward in the Boyle Municipal District.
He says he’ll make a decision in the next couple of weeks.
