Over 30% of Sinn Féin 2020 voters who participated in a Business Post survey now say they are unfit for government.

The latest Business Post/Red C poll shows the party has had a one per-cent decline since September, indicating the recent controversies have not had much impact.

Sinn Féin had been accused of fostering a 'culture of concealment' within the party in regards to the numerous scandals that broke in the past month.

This all comes in the run up to a potential general election, which has yet to be called.

Business Post political correspondent Cónal Thomas says voters' doubts go all the way to the party leader.

“When you dig down into the data, when we asked voters ‘are they fit to be in government’, 53% said they were not,” he said.

“A similar number – exactly 50% – said they did not believe that Mary Lou MacDonald was fit to be Taoiseach.”

Fine Gael continues to lead the way on 22%, down one, with Fianna Fáil up three to 21%.

Independents remain unchanged at 15%.
