López Aliaga leads Lima mayoral exit poll with 31.2%

Voters in Peru went to the polls on October 4 for regional and municipal elections. In Metropolitan Lima, more than 7 million eligible voters chose the next mayor under a first-past-the-post system with no runoff. Polling firm Datum Internacional released an exit poll after voting stations closed at 5:00 p.m.

The exit poll places Rafael López Aliaga of Renovación Popular first with 31.2% of the vote. Francis Allison of Avanza País follows with 25.2%, while Carlos Bruce of Somos Perú trails at 15.9%. Daniel Urresti of Podemos Perú registers 8.7%.

“The vote for Rafael López Aliaga is a very closed, very solid vote that was already manifesting since late August.”

CPI analyst Omar Castro said López Aliaga's support has remained stable around 30% since late August, describing it as a solid, closed vote. He attributed Allison's rise to undecided voters seeking an alternative to the frontrunner.

Renovación Popular also leads in several Lima districts, including Barranco, Breña, Carabayllo, Chorrillos, and Comas. Ate shows a wide lead for Avanza País candidate Manuel Vidal at 63.6%.

The National Office of Electoral Processes (ONPE) will publish official results progressively as tally sheets are processed. The winner will take office on January 1, 2027.
