Senate coup shakes Marcos-Duterte power balance as Sara impeachment nears

MANILA  (May 12) — The Philippines’ political fault lines deepened Monday after allies of detained former president Rodrigo Duterte engineered a dramatic Senate leadership takeover that could reshape the fate of Vice President Sara Duterte and the country’s already volatile political landscape.

In a surprise coup inside the Senate, Tito Sotto was unseated as Senate president and replaced by Alan Peter Cayetano after 13 senators voted for a leadership change.

The political upheaval came at a crucial moment — just as the House of Representatives moved closer to transmitting the Articles of Impeachment against Sara Duterte to the Senate for trial.

The stunning realignment immediately fueled speculation that Duterte allies were consolidating control of the chamber ahead of a possible impeachment showdown that could define the 2028 presidential race and the future of the Marcos-Duterte alliance.

Sen. Imee Marcos formally nominated Cayetano, who secured 13 votes against Sotto’s nine. Senators JV Ejercito and Miguel Zubiri abstained.

The optics of the transition underscored the emerging political bloc: Sen. Camille Villar administered Cayetano’s oath while his sister, Sen. Pia Cayetano, and wife, Taguig Mayor Lani Cayetano, stood beside him.

Cayetano denied the leadership shakeup was connected to Sara Duterte’s impeachment, insisting the country faced larger crises, including conflict in the Middle East, hunger, and threats posed by artificial intelligence.

Still, his remarks signaled clear caution against using impeachment as a political weapon.

“Hindi natin pwedeng sabihin she or he will make a bad president… impeach na lang natin. Hindi po,” Cayetano said, warning against reducing impeachment into a shortcut for eliminating political rivals.

“The Senate is also on trial,” he added.

The leadership coup is widely seen as a major political victory for the Duterte camp, which has been under mounting legal and political pressure following Rodrigo Duterte’s detention and the impeachment complaints hounding the vice president.

Sara Duterte faces accusations ranging from misuse of confidential funds and bribery to unexplained wealth and alleged threats against Ferdinand Marcos Jr..

The shakeup also marked the dramatic return of Ronald dela Rosa, one of Duterte’s staunchest allies, after months away from public view.

An emotional dela Rosa claimed during plenary debates that agents from the National Bureau of Investigation had attempted to block his entry into the Senate complex.

His absence from public life had fueled speculation after Ombudsman Jesus Crispin Remulla earlier disclosed that the International Criminal Court issued an arrest warrant against the former police chief linked to the Duterte administration’s bloody drug war.

Beyond the halls of Congress, the Senate upheaval is expected to ripple across local political networks nationwide, especially in Mindanao where Duterte allies continue to command strong grassroots support.

Analysts say the leadership shift could further polarize communities already divided between the Marcos and Duterte camps, while adding uncertainty to governance, economic priorities, and investor confidence ahead of the 2028 elections.

For many Filipinos, Monday’s Senate coup was more than a change in leadership — it was another sign that the country’s political battle lines are hardening, with impeachment, dynasties, and succession politics now colliding at the center of national power.
