A new opinion poll suggests that Sinn Féin are gaining support at the expense of Fianna Fáil.

The Behaviour and Attitudes poll for tomorrow's Sunday Times newspaper indicates that Sinn Féin have the backing of one quarter of the electorate, putting it firmly in second place.

This day last year, the country went to the polls for what turned out to be one of the most dramatic general elections in decades.

Fianna Fáil's 70-year dominance of Irish politics came to an end, while Fine Gael, Labour and Sinn Féin all won their highest-ever number of seats.

The Behaviour and Attitudes opinion poll in tomorrow's Sunday Times indicates changes in the public’s views in the intervening 12 months.

The poll was carried out among just over 900 voters nationwide between Wednesday 15 February and Monday 20 February. It has a margin of error of plus or minus 3.3%.

Since the last Sunday Times poll in December, just after the Budget, support for Fine Gael has gone up by two points to 32%. Support for their coalition partners Labour has dipped by 1% to 10%.

Fianna Fáil’s support has dropped four points since December, leaving it at 16%. It is a result that will not please the party just a week before their Ard Fheis.

The big winner is Sinn Féin, who have gained at the expense of Fianna Fáil, up four points to 25%.

Independents and others are down one point to 17%.

Satisfaction with all the party leaders has dropped since December, though some have suffered more than others.

Satisfaction with Taoiseach Enda Kenny is down three points to 41%, while Tánaiste Eamon Gilmore drops one to 34%.

Fianna Fáil’s Micheál Martin is down a substantial seven points to 33%, while Gerry Adams is down two to 46%, giving him the highest rating of any leader.

Satisfaction with the Government is unchanged, at 26%, while 70% are dissatisfied, and 3% have no opinion.
