The Irish parliament on Tuesday confirmed Simon Harris as the country’s new prime minister, making him the youngest-ever holder of the position.

Harris succeeds Leo Varadkar as taoiseach — Irish for leader — following a 88-69 vote by lawmakers. He was presented with his seal of office by President Michael D. Higgins on Tuesday afternoon.

Harris said via social media platform X that he was “deeply honoured” to become taoiseach and pledged to “work every day to realise the hopes, dreams and aspirations of all our people.”

Varadkar announced his sudden resignation late last month, surprising the public and politicos alike.

Harris, formerly an education minister, ran unopposed to succeed Varadkar as leader of the center-right Fine Gael party. At 37, Harris will be the youngest-ever taoiseach, taking that record from Varadkar who was 38 when he assumed the post in 2017.

In his first speech after the vote, Harris said he was entering office in a “spirit of humility” and wanted to bring a “new empathy” to public life.

He described housing as the greatest societal issue and committed to “moving mountains” to build new homes. Harris promised to “act decisively” on the climate crisis and to prioritize rural and regional development.

He also spoke of a “humanitarian catastrophe” in the Gaza enclave and condemned the “disproportionate reaction” of the Israeli government to the Oct. 7 atrocities committed by Palestinian militant group Hamas. He added that Ireland would use its position in the European Union to call for a cease-fire.

In a speech last month after becoming presumptive taoiseach-in-waiting, Harris called his nomination an opportunity for the party to “reset.”

“Under my leadership, Fine Gael stands for supporting businesses, especially small businesses… Fine Gael stands for supporting the family farm… Fine Gael stands for law and order, on the side of An Garda Siochána (police), where our streets are safe and crime is never allowed go unchecked,” he said, Reuters reported from a party event.

Fine Gael gained fewer seats in the 2020 election than its conservative rival Fianna Fáil, the other dominant power in Irish politics.

Sinn Féin — running on a platform that included working for unification with Northern Ireland, solving the country’s severe housing crisis and disrupting staid two-party politics — doubled its vote share from 2016 to win the popular vote, according to the Irish Times.

Fine Gael held onto power by entering into a coalition with Fianna Fáil and the Green party.

Harris will have limited time to settle in before heading into an election campaign in which Sinn Féin is likely to emerge as the favorite. A vote must be called by March 22 of next year, and all opposition parties have demanded one after Varadkar’s departure.

Housing is the “obvious challenge” facing Harris, Shana Cohen, director of Irish think tank TASC, said by email, along with “access to health services, meeting carbon emissions targets, and navigating the increasing visibility of the far right.”

“The shortage and cost of housing have had implications for hospital staffing, teachers and younger workers. … Health services in Ireland are supposed to be becoming more accessible and lower cost through the national health policy Slaintecare, but progress has been slow,” Cohen said.

Varadkar received a standing ovation from parliamentarians after giving a farewell speech in the Dáil.

His record was slammed in comments by Sinn Féin leader Mary Lou McDonald, who accused him of failing to fix core issues and said Harris would bring “more of the same” politics. Green party leader Eamon Ryan said Varadkar was leaving the economy in a strong state.

Harris faces an economy in which growth slowed considerably in 2023, ING notes, and which has long raised concerns over its high reliance on multinational corporations.

“With an election in the next 12 months, [Harris’s] focus will be on delivering tangibles including on housing and most likely income tax reductions as part of the budget to be announced in the Autumn,” Diarmaid Sheridan, senior analyst at Davy Research, said by email.

“Foreign direct investment, particularly from American companies, has been the key driver of economic growth in the past decade. That will not change but Harris has indicated that measures will be required for smaller indigenous business who have been impacted by inflation and increased structural cost burdens from increased minimum wages,” Sheridan said.

This support could include VAT reductions or rebates, but these would be temporary measures that may not address structural factors, he added.

In a March report, the Economic and Social Research Institute forecast growth across all main economic activity indicators in 2024 and 2025, and a return to growth in real incomes. It also flagged existing challenges from the cost of living, and a threat from geopolitical tensions and infrastructure bottlenecks in a “small open economy with a very large multinational component.”
