Fine Gael has fallen to its lowest support in a RED C opinion poll since elected in February 2011.

In just two weeks Fine Gael support has dropped four points to 25% when compared to a similar Red C poll for The Sunday Business Post.

This is the lowest level of support for the party in these polls since being elected in 2011.

The debacle over the property tax, water charges and water problems and the decision to go with a referendum on same-sex marriage have all happened in the past two weeks.

Labour sees its support stable at 9% , Fianna Fáil goes up 1% to 24, Sinn Féin drop 1 to 16 and its Independents and others who now command the largest support are up 4 to 26%.
