The first opinion poll since Leo Varadkar's election as Fine Gael leader shows little change in support for the two main parties.

The Behaviour and Attitudes survey, for tomorrow's Sunday Times, shows Fianna Fáil and Fine Gael each with 29%.

Fieldwork for the poll was conducted between 25 May and 6 June, covering the duration of the Fine Gael leadership campaign.

The findings may come as a surprise for Fine Gael members, who might have expected a bounce for the party given the huge media coverage of the campaign and Mr Varadkar's election.

Overall, the poll shows very little movement between all the parties, but the results will reassure Fianna Fáil that they have not lost ground.

When the 'don't knows' are excluded, the findings in this poll compared to the May Behaviour and Attitudes tracking poll show:

Fianna Fail 29% (+2 points)

Fine Gael 29% (+1)

Sinn Fein 18% (unchanged)

Independent Alliance 5% (+1)

Labour 5% (+1)

Greens 3% (+1)

Solidarity/PBP 1% (unchanged)

Other Independents 9% (-3)

Social Democrats 1% (unchanged)
