Fine Gael has benefitted from a slight 'Simon-surge' in the latest poll.
The party is up 3 points to 20% since Simon Harris took over as leader.
However, the Opinions poll in today's Sunday Times shows Sinn Féin is still the most popular party in the country with 27% support, up one point since March.
Fianna Fáil is unchanged on 16% - while the Greens are up one to 6%.
