FIANNA FÁIL REMAINS the most popular political party in the country, according to the latest opinion poll.

Micheál Martin’s party has 29% support, down one percentage point since July but three points ahead of Fine Gael, according to a Sunday Times/Behaviour and Attitudes poll.

Today’s poll marks the fifth consecutive poll of its kind where Fianna Fáil came out on top. Fine Gael’s 26% support remains unchanged since July.

Sinn Féin’s support has increased by six points to 20%, welcome news as the party recovers after a poor performance in May’s local and European elections.

Over 920 adults were interviewed face-to-face for the poll between 5 and 17 September. The margin of error is plus or minus 3.3%.

The results are as follows:

• Fianna Fáil: 29 (-1)
• Fine Gael: 26 (no change)
• Sinn Féin: 20 (+6)
• Independents: 9 (+1)
• Green Party: 5 (-2)
• Independent Alliance: 4 (no change) 
• Labour Party: 3 (-2)
• Solidarity-People Before Profit: 1 (-1)
• Social Democrats 1 (no change) 
• Renua: 1 (+1)
• Aontú: 0

Martin remains the most popular political party leader, with 46% support (down from 49% in July), Taoiseach Leo Varadkar has 40% support (down one point), Sinn Féin’s Mary Lou McDonald’s support is up two points to 38%, and Labour’s Brendan Howlin is down from 41% to 39%.
