A new opinion poll shows a big increase in support for Fianna Fáil over the past month.

However, the Red C poll in tomorrow's Sunday Business Post also showed that two thirds of voters do not have confidence in the Government to manage the economy out of the downturn.

The poll of 1,000 people, which was conducted on Monday, Tuesday and Wednesday, shows that Fianna Fáil is up five points since last month to 28%.

Fine Gael retains the most support and the party gained one point to 31%.

After a big rise last month, Labour support drops a substantial five points to 17%. The Greens are up one point to 7%.

Sinn Féin see a four point drop to 7%, while Independents and others gain two to 10%.

The poll also showed that 66% of voters said they did not have confidence in the Government to manage the public finances out of the downturn.

However, just 30% think Fine Gael and Labour could do any better, while 40% say they would not do better and 30% had no opinion.
