A new opinion poll suggests that Sinn Féin is now the most popular political party in the country.

The Millward Brown poll for the Sunday Independent found it has increased its support, excluding "don't knows", to 26%.

Fine Gael stands at 22%, Fianna Fáil 20%, Labour is at 7% and Independents and Others at 23%.

The poll was carried out over the past ten days with nearly 1,000 people interviewed.

The party support for first preferences, excluding "don't knows", compared to the last opinion poll in September, shows Fine Gael down 3% to 22, Fianna Fáil down one to 20%, Sinn Féin up 4 to 26%, Labour down two from 9 to 7%, with Independents staying the same at 23%.

When asked about party leaders, Enda Kenny is the least popular with 67% saying they are "Dissatisfied" with him as Taoiseach, Fianna Fáil's Micheál Martin the most popular with 54% saying they are "Dissatisfied" with the way he is doing his job.

Both Labour's Joan Burton and Sinn Féin's Gerry Adams scored 56% dissatisfaction.
