Paraguayan conservative economist Santiago Peña won the country’s presidential election on Sunday, tightening the ruling Colorado Party’s political grip in the country.

Peña had 42.7% of the vote with 99.9% of ballots counted, a more than 15-point lead over center-left rival Efrain Alegre.

“Thank you for this Colorado victory, thank you for this Paraguayan victory,” Peña said in a speech. Alegre acknowledged the result. Current President Mario Abdo congratulated Peña as “president-elect”, as did the leaders of Brazil, Lula Da Silva, and Argentina, Alberto Fernández.

Colorado and right-wing party candidates also performed strongly in congressional elections and governor races, with some provinces recording a historic Colorado majority over opposition rivals.
