There has been an increase in support for Fine Gael according to the latest Irish Daily Mail/Ireland Thinks opinion poll.

The survey of voters was carried out over five days on the week that Leo Varadkar succeeded Enda Kenny as Taoiseach.

The controversy surrounding the judicial appointment of former attorney general Máire Whelan only gathered momentum on the final day of this sample of voters' preferences.

It puts Fine Gael on 31%; a six-point increase on the last comparable poll in April.

Fianna Fáil drops one point to stand at 26%.

There is also a one point fall for Sinn Féin, with the party's support measured at 16%.

Labour rises by two points to 7%, while a two-point hike in support for the Green Party puts it on 4%.

The Social Democrats and Solidarity-PBP are each on 2%.

Support for independents and others fell by four points to stand at 11%.

The margin of error in this poll of 1,300 voters is 2.8%.
