A new opinion poll suggests that the Fianna Fáil leader Micheál Martin holds a commanding 11-point lead over the Taoiseach Leo Varadkar when it comes to public satisfaction with party leaders.

The Behaviour & Attitudes Poll for tomorrow's Sunday Times, found that 54% of those questioned were satisfied with the Fianna Fáil leader - that is up two points on the previous poll.

In contrast, Leo Varadkar secured 43% for his stewardship of Fine Gael. However, that is a six-point increase on what former Taoiseach Enda Kenny got last time out.

The Sinn Féin leader Gerry Adams secured 43%, while the Labour leader Brendan Howlin was one point behind on 42%.

The research for the poll was conducted between 29 June and 11 July.

When it comes to party support, the poll found that Fianna Fáil has edged ahead of Fine Gael.

The poll put Fianna Fáil up one point on 30% while Fine Gael remains unchanged on 29%.

Sinn Féin is unchanged at 18%, as is Labour on 5%. Others are at 19%. 

The poll also shows the Government's approval rating has increased four points and now stands at 39%.
