There are no post-Budget gains for either Fine Gael or Fianna Fáil, according to the latest Sunday Business Post/RED C opinion poll. 

Support for both parties and Sinn Féin dropped slightly in this survey of voters carried during the week.

The opinion poll shows that the Budget has had little or no impact on people's voting preferences.

Fine Gael drop one point to 29% but remains the most popular party.

Although Fianna Fáil had a key role in shaping the Budget, the party also dropped one percentage point to 25%.

Sinn Féin is down two points to 14%, that's the party's lowest level of support this year in this series of polls.

Both the independents and the Independent Alliance are each up two points to stand at 12% and 4% respectively.

The Labour Party is up one point to 6% while Solidarity-PBP are unchanged at 4%.

The Green Party, on 4%, gains two points while support for the Social Democrats, on 2%, is down two.

All changes in this poll are within the 3% margin of error.
