Mayo FG Councillor Cyril Burke is facing an internal party disciplinary hearing, after findings were made against him by the State's ethics watchdog.
Councillor Burke was found to have breached Standards in Public Office Commission rules arising from his involvement in an alleged plan to secure zoning for land owned by another councillor.
SIPO found Councillor Cyril Burke acted in contravention of the code of conduct for politicians, in his dealings with Independent Councillor Frank Durcan, who also had findings made against him.
Fine Gael's national executive has now decided to refer Cyril Burke to the party's disciplinary committee.
The matter is due to be debated this evening at the monthly meeting of Mayo County Council in Castlebar.
Outside the council offices, a protest is taking place this afternoon in relation the SIPO findings against the two councillors.
People Before Profit candidate in the Castlebar area Joe Daly, who's organised the demonstration, is calling for Councillors Burke and Durcan to resign over the matter.
