Fine Gael could be on course to form a government on its own, according to the latest Red C poll in tomorrow’s Sunday Business Post.

The Red C poll for tomorrow's Sunday Business Post shows support for the party rising, while the other main parties drop back.

This Red C poll was carried out on Tuesday, Wednesday and Thursday, so it should take fairly full account of the impact of the TV3 Leaders' Debate on Tuesday night, and of the criticism of Enda Kenny for not taking part in it.

Red C polled more than one thousand voters around the country, and found the number undecided down three points since last week, to 17%.

When they are excluded, support for Fine Gael is up three points to 38% - the kind of figure that makes a single party government a possibility.

Labour falls two points to 20, while Fianna Fáil is also down two, to 15%, and Sinn Féin drop three points to 10%.

The Greens are up one, to three, while Independents and others gain three to 14% support.
