The daughter of Philippine President Rodrigo Duterte announced her candidacy for vice president on Saturday, putting an end to months of speculation about her 2022 election aspirations.

Sara Duterte-Carpio, 43, entered the vice presidential campaign as a replacement after her political party’s initial candidate withdrew, according to her spokesman, Mayor Christina Garcia- Frasco.

The political party of Ferdinand Marcos Jr., the son and namesake of the late Philippine dictator who has registered to run for president, chose Duterte-Carpio as its vice presidential candidate shortly after her nomination papers were filed through a representative.

Garcia-Frasco said Duterte-Carpio would be releasing a statement shortly.

Duterte-Carpio’s decision to seek the country’s No. 2 job came as a surprise as she has led opinion polls throughout this year as the preferred presidential candidate.

“It was a surprise,” Antonio La Vina, professor of law and politics at the Ateneo de Manila University told Reuters. “Next surprise is VP for whom.”

In the Philippines, president is elected separately from the vice president.

Duterte-Carpio’s 76-year-old father is barred by the Constitution from seeking a second six-year term. He said last month he was retiring from politics.

The Southeast Asian nation of 110 million people holds elections in May 2022 for positions from president down to governors, mayors and local officials.

Apart from Marcos, other presidential aspirants in next year’s polls include former boxing champion Manny Pacquiao, vice president Leni Robredo, Manila mayor Francisco Domagoso, senator Panfilo Lacson, and Duterte’s former police chief Ronald dela Rosa.
