The junior Finance Minister said the Justice Minister has answered questions about why he failed a breathalyser test at a Garda checkpoint on his way home from the Dáil, but if there are further questions about the incident, he will answer them.
Minister Shatter said yesterday he failed the test because he has asthma, after Independent TD Mattie McGrath raised the issue in the Dáil.
It is expected Minister Shatter will face questions from opposition parties - including why he mentioned to the officer that he was on his way home from Leinster House.
Junior Finance Minister Brian Hayes said that if there are genuine questions to be answered, Minister Shatter will do so.
"If there is any other questions to genuinely ask about this Alan Shatter will answer them, he spent the whole week answering questions in the Dáil and on the media," he said.
"And he has done a very good job of it quite frankly."
