Fine Gael remains the most popular political party in the country, according to two new opinoins polls.

But the polls in tomorrow's Sunday Times and Sunday Business Post offer mixed messages about the performance of the Labour Party.

One poll says the party is down two percentage points; the other says support has grown by two points.

Our political correspondent Gavan Reilly reports:

Two papers, two polls, and two wildly different oucomes.

The Red C poll for the Sunday Business Post has Labour up two points, to 11 per cent, while Fine Gael are also up two to 29.

It says Fianna Fáil has slipped one to 22, while Sinn Féin are steady on 16 and others down three to 22.

But the Sunday Times poll from Behaviour and Attidudes says Labour are down two points to 9, while Fine Gael are unchanged at 30.

It says Fianna Fáil are down 2 to 19 - even though it says Micheal Martin is the most popular party leader - while Sinn Féin rise three to 18 and others stay on 24.

There is at least one consistent sign - the Sunday Business Post marks the second poll this week on gay marriage.

And for the second time this week, it's found that 76 per cent of the public are in favour of full same-sex marriage
