Sara Duterte Impeachment Trial Opens, Putting 2028 Philippine Election in Focus

The impeachment trial of Philippine Vice President Sara Duterte officially began on Monday, marking the first impeachment proceedings against a sitting vice president in the country's history. The closely watched case is expected to play a major role in shaping the political landscape ahead of the 2028 presidential election.

Prosecutors described the trial as a critical test of accountability and public trust, while Duterte's legal team argued the impeachment is a politically motivated effort to remove a leader elected by more than 32 million Filipinos.

The Senate proceedings opened amid sharp political divisions, with lawmakers debating procedural issues, including the selection of the presiding officer, delaying the start of the trial.

Duterte faces allegations of misusing public funds, amassing unexplained wealth, bribery, corruption, and threatening President Ferdinand Marcos Jr., the first lady, and a former House speaker. Prosecutor and Congresswoman Gerville Luistro told senator-judges that the accusations form "four chapters of the same story" centered on a betrayal of public trust. She described Duterte's alleged threats against the president as the most serious charge, arguing that her own recorded public statements provide key evidence.

The once-powerful Marcos-Duterte alliance, which secured victory in the 2022 elections, has since collapsed following an increasingly bitter political feud. Tensions escalated after former President Rodrigo Duterte, Sara Duterte's father, was transferred to the custody of the International Criminal Court last year.

Sara Duterte has denied all allegations, insisting prosecutors bear the burden of proof. She skipped Monday's proceedings but said appearing through legal counsel does not reduce her accountability or transparency.

The trial is expected to last at least three months and could significantly affect Duterte's presidential ambitions after she announced plans to seek the country's top office in 2028. Political analysts say the credibility of the Senate trial will be crucial, as a fair acquittal could strengthen her candidacy, while a politically disputed outcome could leave lasting questions regardless of the verdict.

A conviction requires the support of at least 16 of the Senate's 24 members. The result could also influence who eventually leads the Marcos political camp in the 2028 presidential race, as President Marcos is constitutionally barred from seeking another term.
