His election follows Leo Varadkar, who became Prime Minister at 38. Harris’s rise comes amid hopes of revitalizing his party's declining popularity with his social media fluency and innovative approach.

After Varadkar’s unexpected resignation, Harris quickly emerged as the favorite to lead the Fine Gael party, securing widespread support by Thursday and officially being confirmed on Sunday.

Harris commits to addressing law and order, sustainable immigration, and combating populism. His journey to becoming Taoiseach, marked by a swift political ascent, began in Greystones, where he grew into politics advocating for autism services inspired by his brother.

At 24, Harris became the youngest MP in 2011, later serving as Health Minister where he faced both praise and criticism, particularly during the Covid pandemic.

Despite controversies, Harris’s effective communication, especially on platforms like TikTok where he enjoys considerable popularity, has been a notable aspect of his political career.

Married with two children, Harris is recognized for his ability to connect with the younger audience, even amidst accusations of pandering. As Fine Gael prepares for upcoming elections, Harris’s youthful energy and strategic approach are seen by some as key to reinvigorating the party.
