The Philippine Senate on Thursday removed pro-Duterte Senator Alan Peter Cayetano as its president and elected Sherwin “Win” Gatchalian, a shift that could determine the outcome of Vice President Sara Duterte’s upcoming impeachment trial, according to official records and reports from Rappler.
How did the Senate leadership change unfold?
The 13 senators present during a special session voted to install Gatchalian as Senate president after pro-Duterte Senator Joel Villanueva switched allegiance, according to GMA News Online. Villanueva’s decision followed negotiations with Gatchalian’s bloc, which had previously challenged Cayetano’s leadership. Cayetano, who seized the presidency in May through a procedural maneuver, conceded after Villanueva informed him of his support for Gatchalian, Rappler reported.
What triggered the power struggle?
The conflict stems from a broader political rivalry between President Ferdinand Marcos Jr. and the Duterte family, which has intensified as the Senate prepares to begin Sara Duterte’s impeachment trial on July 6. The trial, initiated by the House of Representatives in May, accuses the vice president of corruption, misuse of funds, and plotting to assassinate Marcos. A conviction requires at least 18 of 24 senators’ votes, Philippine Daily Inquirer reported.
How does this affect the impeachment trial?
Gatchalian’s ascension could tilt the Senate’s balance of power. His bloc has criticized Cayetano’s leadership as an “illegal coup d’état,” while pro-Duterte senators argue the trial is politically motivated to undermine Sara Duterte’s 2028 presidential prospects. The outcome hinges on alliances, with key figures like Senator Ronald “Bato” dela Rosa—currently in hiding over an ICC warrant—having previously influenced Senate decisions, BBC News noted.
What other political developments are linked?
Separately, pro-Duterte Senator Jose “Jinggoy” Estrada surrendered to police in June after an anti-graft court ordered his arrest over a $9.3 million kickback scandal, GMA News Online reported. Villanueva, meanwhile, faces Justice Department probes over flood control corruption, though his Senate vote shift remains unexplained.
Why does this matter for Philippine politics?
The Senate’s leadership change underscores the high stakes of the impeachment trial, which could reshape the country’s political landscape. A conviction would bar Sara Duterte from future office, while her allies argue the proceedings lack due process. The dispute reflects deeper tensions between Marcos’s administration and the Duterte faction, Al Jazeera observed.
