Micheal Martin has been elected as Taoiseach by the Dáil.
He was elected by 95 votes to 76 following a roll-call vote this afternoon.
He will proceed to Aras an Uachtarán to receive his seal of office from the President.
In a speech, the Taoiseach says: "As I look at Ireland today, it is clear that there can be a degree of cynicism towards politics. Too often we dismiss the motivation of others, especially those we disagree with.
"I reject this. I believe in the good faith of those who seek to serve their communities in elective office – and I believe that politics remains a force for good, a force for positive change.
"I hope that we can have a cooperative Oireachtas in the coming years, where we try to emphasise positive discussion.
"For my part I intend to remain open to constructive ideas from Deputies from all parts of the House."
