Fine Gael is still the most popular party in the country, according to the latest opinion poll.

Despite a small dip in support, the poll shows Leo Varadkar's party still has a seven point lead over Fianna Fáil.

The Sunday Business Post / Red C poll shows Fine Gael on 32%, which is down a point - with Fianna Fáil up one at 25%.

There's disappointment for Sinn Féin, which has dropped the two point gain it made in last month's poll - the party is now down two points to 14%.

Independents are up two points to 13%.

The row in the Independent Alliance and the unclear nature of Sean Canney's future in the group hasn't had any impact on the electorate, with the Independent Alliance actually up a point to 2%.

Labour is unchanged on 6%, while the Green Party, the Social Democrats and Solidarity-People Before Profit all remain on 2%.

Renua, the only party actively campaigning for a 'No' vote in the Eighth Amendment referendum, is down by one point to 1%.

The telephone poll of 1,000 voters was carried out between Thursday April 19 and Thursday April 25 last.

Sunday Business Post political editor Michael Brennan said: "It's a minor boost for Fianna Fáil... their support had dropped a lot in the last poll. But they're still trailing behind Fine Gael.

"On these sort of figures, they'll have to stick with the confidence and supply arrangement a bit longer before they risk trying to get into a general election situation."
