Environment Minister Alan Kelly has been accused of swearing at another TD in the Dáil.
It is believed Alan Kelly told his Tipperary colleague Mattie McGrath to "Eff off" during a debate on Irish Water.
The minister later said he didn't recall making the remark, and apologised if he had done so.
Deputy McGrath was not pleased.
"It has been brought to me attention that a few minutes ago during my contribution, that Minister Alan Kelly expressed a very nasty expletive to me across the house.
"I didn’t hear it, but I want the records checked and I want an apology if he used that kind of foul language to me as an elected representative of the people of Tipperary."
