Tanaiste Leo Varadkar labelled Social Democrats co-leader Róisín Shortall as a "hypocrite" during a tense exchange during Leaders' Questions in the Dáil on Thursday afternoon.
With Taoiseach Micheál Martin in the UK to meet new British Prime Minister Rishi Sunak for the first time, the Fine Gael leader was in his place to take questions from TDs.
But during the session, he was involved in a clash with Ms Shortall in relation to the decision of the Standards in Public Office Commission (SIPO) on Wednesday evening.
