Leo Varadkar has promised new hope and opportunities for the people of Ireland as he became the country's premier for a second time.
In a planned handover of power at the top of the ruling three-party coalition government in Dublin, Fine Gael leader Mr Varadkar replaced Fianna Fail leader Micheal Martin as Taoiseach on Saturday.
Irish parliamentarians in the Dail voted 87 to 62 to support his appointment in a special sitting.
