Heather Humphreys, who has been appointed Minister for Business on Thursday, was first elected a TD in the Cavan-Monaghan constituency in 2011.
Ms Humphreys was the first woman to be elected for Fine Gael in the constituency. Since 2011, she has served as Minister for Arts, Heritage and the Gaeltacht.
She was embroiled in controversy when Fine Gael nominee John McNulty was appointed to the board of the Irish Museum of Modern Art in advance of a Seanad byelection he was contesting for Fine Gael.
He later resigned and withdrew from the byelection.
She was also in charge of the commemoration of the 1916 Rising. This drew widespread praise, although she also found herself on the wrong side of a High Court ruling on the preservation of the Moore Street “battle field” site in 2016.
Ms Humphreys was co-opted to Monaghan Co Council in 2003 and was re-elected in 2004 and 2009. She served one term as mayor.
