The Taoiseach has pledged his support for the Justice Minister.
Alan Shatter is to face a Fianna Fáil motion of no confidence in the Dáil next week as the controversy over his breathalyser continues.
Enda Kenny has revealed this evening that the Minister made two attempts to blow into the bag when he was stopped at a garda checkpoint sometime in 2008 or 2009.
Alan Shatter said that he could not complete the test because of his asthma and was waved on after telling gardaí he was on his way home from the Dáil.
However the Taoiseach stopped short of stating the Minster had his 100% support, but he said that government will fight what he has called Fianna Fail opportunism.
"The government will refute strongly a political opportunism by Fianna Fáil in terms of a private members motion," he said.
"Minister Shatter has set out the most reforming agenda for the legal system in this country in the past 200 years
"The government look forward indeed to dealing with the motion of no confidence when it comes forward next week."
