Three opinion polls to be published tomorrow show the Government parties struggling for support.
The findings will be of particular concern to the Labour Party which had a backing of 5 per cent in two of the polls and 6 per cent in the other.
All three studies show Independents and Others to be the most popular political grouping.
Support for Sinn Féin is up in two of the polls and down significantly in the third. Fianna Fáil is up in one poll, down in another and unchanged in the third.
A Behaviours & Attitudes poll for The Sunday Times shows Fine Gael on 24 per cent (-1 since the last poll two months ago); Fianna Fáil on 18 per cent (no change); Sinn Féin on 22 per cent (+3); Labour on 5 per cent (-4); the Green Party on 1 per cent (-2); and Independents and Others 29 per cent (+4).
A Red C poll for the Sunday Business Post puts Fine Gael on 21 per cent (-1 since the last poll four weeks ago); Fianna Fáil on 19 per cent (+1); Sinn Féin on 24 per cent (+2); Labour on 6 per cent (-2); and Independents and Others at 30 per cent (no change).
