Sinn Féin leader Gerry Adams has seen his satisfaction rating drop by six points in the last month according to a new opinion poll.

The Behaviour and Attitudes poll in tomorrow's Sunday Times indicates the Sinn Fein TD's rating has dropped six points down to 32.

The poll was taken during extensive coverage of the 1983 IRA shooting of Brian Stack, on which Gerry Adams made a Dáil statement.

Taoiseach Enda Kenny is on 33 points - a rise of one point since last month's survey.

Fianna Fail's Micheál Martin is the country's most popular political leader on 50 points, with Labour's Brendan Howlin on 39.

Fianna Fáil is also the country’s most popular political party despite a two point drop in favour to 28%.

Fine Gael is the second most popular party at 26% having also suffered a two point drop.

Sinn Féin came in third at 19% after a two point rise in popularity while the Labour Party is at 5%.

The government’s satisfaction rating as a whole remained at 34%.

Stephen O'Brien, political editor of the Sunday Times, said Deputy Adams' performance in the poll may lead to more questions over his future leadership of Sinn Fein:

“Adams has fallen six points,” he said. “But it is equally striking, given that that has happened, that Sinn Féin is up two points in the same series.”

“[Sinn Féin] is up to 19% which is its best number for more than a year in the Behaviour and Attitudes Sunday Times poll.

“Perhaps that might ease the pressure internally in Sinn Féin to replace Mr Adams very quickly although I think the pressure to replace him before the next general election will remain.”

The poll was based on sample of over 1,000 eligible Irish voters over the period Nov 29th - Dec 13th.
