The Philippine Senate has opened an impeachment trial against Vice President Sara Duterte over allegations of fund misuse and assassination plots [1].

The proceedings represent a critical constitutional crisis in Manila, as the trial seeks to determine if one of the country's highest elected officials betrayed the public trust. The outcome could shift the balance of power between the executive branch and the legislature.

The trial began on July 5, 2026 [1]. Prosecutors said that Duterte misused confidential funds and accumulated unexplained wealth [1], [2]. Most severe is the accusation that the vice president was involved in a plot to hire a hitman to assassinate President Ferdinand Marcos Jr. [1], [3].

Defense attorneys have countered these claims, saying the trial is a politically motivated effort to remove an elected official from office [1], [2]. They said that more than 32 million people elected the vice president [1].

The proceedings are taking place in the Philippine Senate chamber in Manila [3]. By July 8, 2026, the trial had reached its fourth day [2]. Due to the political volatility of the case, thousands of police officers have been deployed to maintain order [3].

The Senate remains divided as it weighs the evidence presented by prosecutors against the defense's claims of political persecution [1]. The trial's progression depends on the ability of the prosecution to substantiate the claims regarding the hitman plot, and the origin of the vice president's wealth [2].

The trial seeks to determine if one of the country's highest elected officials betrayed the public trust.

This trial signals a definitive collapse of the political alliance between the Duterte and Marcos families. By combining financial crimes with an alleged assassination plot, the prosecution is attempting to establish a legal basis for removal that transcends simple political disagreement, potentially setting a precedent for how the Philippine Senate handles high-level executive misconduct.
