A new opinion poll indicates a Fine Gael lead over Fianna Fáil has halved in the last month.

In September the Sunday Times/Behaviour & Attitudes poll gave Fine Gael an eight point lead over the main opposition party.

This new poll puts the lead at four points.

The poll, based on face to face interviews with over 900 voters was conducted between 2 October and 10 October.

Compared to the September poll it shows Fine Gael is down two points to 31% while Fianna Fáil is up two points to 27%.

At 19%, there is no change for Sinn Féin.

Independents are up two points to 12% while the Labour Party is down one point to 4%.

There is no change for the Social Democrats at 1%.

Solidarity/People Before Profit are up one point at 1%.

There is no change for either the Green Party at 2% or for the Independent Alliance at 3%.

As the majority of fieldwork for this poll was conducted before Budget day it does not capture the full public response to the measures announced by Finance Minister Paschal Donohoe.

The margin of error for the poll is plus/minus 3%.
