Leo Varadkar has been announced as the leader of the biggest party in Ireland’s ruling coalition, Fine Gael.
Mr Varadkar beat his rival, Housing Minister Simon Coveney, with 60% of the votes. He will become Ireland’s first gay taoiseach (prime minister).
He is expected to take over from former Fine Gael leader, Enda Kenny, in the next few weeks.
At 38, he will also be Ireland’s youngest ever prime minister.
The leadership was decided in an electoral college system that gives 65% of the vote to the Fine Gael parliamentary party – made up of 73 TDs (members of the Irish assembly), senators and MEPs.
The party’s 21,000 rank-and-file members have 25% of the vote, and 235 local representatives 10%.
Mr Varadkar took a commanding lead on the first day of the contest after winning the public support of many of Fine Gael’s TDs (MPs).
Mr Coveney vowed to remain in the contest, and told RTE he remained optimistic about his chance in the leadership race.
Independents to approve new taoiseach
Mr Varadkar, who came out as gay in the run up to the 2015 same-sex marriage referendum, has been in charge of the welfare system.
He has come to personify the liberalisation of a country which was once regarded as one of Europe’s most socially conservative nations – homosexuality was illegal until 1993.
However, Mr Varadkar has come under criticism for his comments on progressive issues and workers’ rights.
The new Fine Gael leader will have to be endorsed by the independent members of the minority coalition government before he becomes taoiseach. That’s expected to happen later this month.
Enda Kenny, 66, who led the party for 15 years and was elected taoiseach in 2011, resigned as Fine Gael leader in May.
Voting took place this week around the country.
