Enda Kenny has become Fine Gael's longest serving Taoiseach, having equalled the record of John A Costello yesterday.
Today is Mr Kenny's 2,234th day in office.
He was first elected on 9 March 2011 and has served continuously since.
Mr Kenny was elected leader of Fine Gael in June 2002.
A spokesperson for the Taoiseach said Mr Kenny has no interest in records or runs, and his focus is on the job and particularly the implications of Brexit.
