The latest opinion poll on the 26 Counties ahead of June local and European elections indicate that Sinn Féin, the Green Party and possibly Labour will gain on many local authorities.
The main opposition Fine Gael could lose to one third of its council seats and appears to be in continuing decline.
Sunday's opinion poll shows that support for the governing Fianna Fail party is at 34 per cent for the local elections and 36 per cent for the Euro elections is below its 1999 result, but has recoved lost ground. The Fianna Fail annual conference, just days before the poll was taken, may have given the party a short-term boost.
At 11%, Sinn Féin now enjoys the fourth largest support of any party and is challenging the Labour Party, who are at 12%, for third place. The strong result is in spite of the recent government offensive against the party.
However, an apparent decline in support for Sinn Féin in Dublin suggests it still has work to do to secure a place in the European Parliament for its candidate, Mary Lou McDonald.
Fine Gael is on course to suffer disastrous losses in June, registering at 22 per cent for support in the local elections and 21 per cent in the European elections.
Support for the Progressive Democrats is steady at 4 per cent, while the Greens are up to 7 per cent.
