MANILA - Incoming President Rodrigo Duterte's victory is the triumph of the people, his spokesman said Friday night.

Peter Lavina, Duterte campaign spokesperson, issued the statement after Duterte and Rep. Leni Robredo emerged as winners in the May 9 presidential and vice-presidential elections, respectively, based on the final tally of votes by Congress sitting as the National Board of Canvassers.

"Finally victory has been achieved. The official results of 2016 presidential race with Rody Duterte as winner may be anti climactic, but we should not lose its historic significance," Lavina said.

"His victory is the triumph of the people, by the people and for the people. Let us celebrate this milestone of Philippine democracy by uniting and working for genuine change," he added.

The proclamation of Duterte and Robredo by Congress is expected on Monday.

However, Duterte's aide Bong Go said the incoming president won't attend the proclamation.

Duterte won the presidency with his pro-federalism and anti-crime campaign, backed by his track record in leading Davao City for more than 20 years.

Robredo, a lawmaker from Camarines Sur, was thrust into the national scene after her husband, Interior Secretary Jesse Robredo, died in a plane crash in August 2012. She campaigned on Aquino's platform of Daang Matuwid, and will be the Philippines' first Bicolano vice-president. -with reports from Dharel Placido and Dexter Ganibe, ABS-CBN News
