A new opinion poll suggests that the gap between Fine Gael and the two main opposition parties has narrowed.

The Behaviour and Attitudes poll for the Sunday Times was conducted in the period running up to the announcement of the draft Brexit withdrawal deal last Tuesday.

It shows Fine Gael is down one point on 30% while Fianna Fáil is unchanged at 27%.

Meanwhile, Sinn Féin shows the biggest gain, up four points to 23%.

The Independents are unchanged at 9%, as is the Labour Party on 6%.

Solidarity/People Before Profit see no change at 2% while the Independent Alliance and the Green Party are both down one point to 1%.

The Social Democrats are up one, to 1%.

The poll was sampled from 1-13 November and is based on face-to-face interviews with 905 eligible Irish voters. It has a margin of error of 3.3%.

The figures compare with a similar poll conducted in October.
