Keiko Fujimori was sworn in as Peru's president on Tuesday, becoming the country's ninth head of state in a decade after winning a June runoff by fewer than 50,000 votes. The inauguration marks a significant moment for Peru's often turbulent politics, given that only three presidents in the past ten years have been chosen by popular vote, and it aligns with a broader conservative trend across South America following similar election wins in Colombia and Chile.

Fujimori, 51, is a four-time presidential candidate and leader of Popular Force, the country's largest party, which together with ally Popular Renewal will control half the senate seats, offering her a degree of political stability. She has pledged an "iron fist" approach to crime modelled on El Salvador's President Nayib Bukele, including building a large new prison inspired by El Salvador's Cecot facility, alongside promises of infrastructure investment, judicial reforms to protect judges, a 15% minimum wage rise and measures to tackle rural malnutrition. She is the daughter of former President Alberto Fujimori, who was imprisoned for human rights abuses before being pardoned in December 2023 and dying in September 2024; her own inauguration was met with protests from left-wing opponents contesting the election result and demanding investigation into 50 civilian deaths during 2022-2023 anti-government demonstrations.
