Simon Harris, at 37, is poised to become Ireland's youngest Prime Minister as the newly elected leader of Fine Gael, succeeding Leo Varadkar.

Harris vowed to invigorate Fine Gael with energy and renewal, committing to the current government's program and policies supportive of small businesses, work appreciation, and educational development.

He advocates for a pro-European agenda and a more structured and sustainable approach to immigration.

Harris faces challenges such as tackling the housing crisis and homelessness, and must secure public support in the wake of Fine Gael's drop to third place in the 2020 elections.

Leo Varadkar's departure marks the end of a historic tenure as Ireland's youngest, first openly gay, and first biracial Prime Minister.

Harris is expected to be officially instated as Prime Minister in early April and has expressed his determination to combat populism and polarization.
