The 37-year-old Simon Harris is set to become Ireland's youngest taoiseach (prime minister) after being officially named as the new leader of Fine Gael. Only Mr. Harris, an Irish minister in the cabinet, ran for the party leadership. Leo Varadkar, the party's leader and taoiseach, said on Wednesday that he was stepping down. He will be replaced by him. In a speech, Mr. Harris outlines his top priorities. He said becoming leader of the party "is the honour of my life to lead this great party, our great party, Fine Gael". He thanked the party and those that elected him for trusting him, adding that he will "repay that trust in hard work". "With blood, sweat and tears - day in and day out - with responsibility, with humility and with civility," he added. Mr Harris is not expected to making any final decisions on his cabinet until the Dáil (Irish parliament) is back on 9 April. Nominations for the Fine Gael leadership closed at 13:00 local time on Sunday. He was the only candidate for the position at the close of nominations.
