Keiko Fujimori has been officially declared the winner of Peru’s presidential race by the electoral authority, securing 50.135% of the vote against leftist candidate Roberto Sánchez, who garnered 49.865%. This tight result represents a margin of less than 50,000 votes out of approximately 18 million cast in the June 7 runoff election. Fujimori's victory comes after weeks of contentious ballot reviews and accusations of fraud, illustrating the deep political polarization in the country, according to Al Jazeera, Reuters, Le Monde, and BBC.

Fujimori, the daughter of former President Alberto Fujimori, has a controversial political background, having previously run unsuccessfully in three elections. She aims to tackle organized crime and unite a country beset by political instability, stating, "A new chapter begins. We take it on with responsibility, humility, and a deep sense of duty." Her platform emphasizes a military crackdown on crime and attracting private investment to stimulate economic growth, especially given the challenges posed by chronic instability, according to Al Jazeera, Reuters, and BBC.

The electoral results reflect a significant shift towards conservative leadership in Latin America, coinciding with the election of right-wing leaders in Colombia and other regional nations. Following her victory, Fujimori received congratulations from various conservative leaders, including Argentina's Javier Milei and US Secretary of State Marco Rubio, who expressed eagerness to deepen cooperation on security and trade, according to Reuters, Le Monde, and BBC.

Fujimori is expected to assume office on July 28, becoming Peru's tenth president since 2016, amidst a fragmented Congress and ongoing challenges such as economic divides and security threats. Her administration’s success will likely depend on her ability to navigate these complexities, especially with the opposition party under Sánchez, who has threatened to contest the election results further, according to Al Jazeera, Reuters, Le Monde, and BBC.
