Castlerea’s Seamus O’Brien, Ballaghaderreen’s Michael Mulligan and Monksland’s Joe Harney are set to be confirmed as Sinn Féin’s local elections candidates later this week.
The party is holding a selection convention for the three Roscommon areas on Friday night in Gleeson’s Restaurant and Rooms in Roscommon town.
Nominations close tonight, but it’s likely Mr Mulligan, a sitting councillor, will be selected for Boyle.
Mr O’Brien, who narrowly lost out in 2014, is tipped to be chosen for Roscommon and community activist Mr Harney for Athlone.
Claire Kerrane is a spokesperson for Roscommon Sinn Féin.
