Leo Varadkar represents "liberalisation" in Ireland and his election as the new Fine Gael leader is a "significant step forward for equality" - these are just some of the reactions from international news agencies.
As Varadkar beat rival Simon Coveney to head the party, the world's media wasted no time responding to the news.
The Guardian said: "The son of an Indian immigrant who came out as gay in 2015 will be the next Irish prime minister, after he was voted leader of the country’s main governing party on Friday.
"Leo Varadkar’s victory in the Fine Gael leadership contest, which took place after outgoing PM Enda Kenny announced his resignation last month, marks another significant step forward for equality in the country, after 2015’s gay marriage referendum.
"As well as becoming Ireland’s first gay prime minister, Varadkar, 38, will also become the country’s youngest leader, and the first from an ethnic minority background.
"His position will be confirmed later this month when parliament resumes after a break."
BBC News also described his election as a progressive move.
They said: "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."
ITV echoed these sentiments as they said Varadkar is placed as the best figure to take the party into the next election.
They said: "Many in the party believe the Dublin-born-and-raised Mr Varadkar is representative of an urban, progressive generation that can help sell the party to the wider electorate at the next election.
"Although he had rallied for the change in marriage law in public, he remains otherwise private about his personal life, though he is known to have been in a relationship with another medic for two years."
BBC did note that some of his policies as Social Protection Minister have proven controversial.
They said: "Mr Varadkar has come under criticism for his comments on progressive issues and workers' rights."
Meanwhile, in India there has also been widespread coverage of Mr Varadkar's election as party leader.
The Times of India reports:
"Ireland's governing Fine Gael party elected Leo Varadkar as its new leader on Friday, choosing the gay, 38-year-old son of an Indian immigrant to succeed Enda Kenny as prime minister in a striking sign of the country's rapid social change."
In the United States the New York Times is also reporting on the new Fine Gael leader running an article entytitled: Gay Lawmaker, Leo Varadkar, Is in Line to Be Ireland’s Prime Minister
The paper reports his election in the context that Ireland is a "country that has rapidly been leaving its conservative Roman Catholic social traditions behind".
Broadcaster CNN is also reporting the news and focusing on the fact that Mr Varadkar is gay, running the following headline: Ireland's next prime minister is a conservative, gay 38-year-old.
"Varadkar might seem to be an unexpected pick for leader of Ireland -- a country that's still finding its secular European footing after years of church influence over the state. But Varadkar's policies signal a sharp move towards the right," Kara Fox writes.
