MANILA, Philippines — Despite intense backroom negotiations and persistent rumors of a counter-coup, Alan Peter Cayetano maintained his hold on the Senate presidency as the upper chamber resumed its session. Cayetano presided over the historic convening of the Senate impeachment court on Monday, May 18, 2026, multiple political sources confirmed that high-stakes talks regarding his potential replacement were occurring just hours before the plenary bell rang.
The unease within the leadership highlights a deeply volatile majority bloc, fractured by controversial legal stances, domestic scandals, and a looming trial.
Cayetano’s position at the helm of the Senate remains highly fragile due to the chaotic nature of his sudden rise to power just one week prior:
- The Crucial 13th Vote: Cayetano secured the Senate presidency on May 11, 2026, through a swift, aggressive leadership coup that ousted Vicente “Tito” Sotto III. The move succeeded by the narrowest of margins, depending entirely on the unexpected reappearance of Senator Ronald “Bato” dela Rosa, who had been hiding for six months to evade an international arrest warrant.
- The Protective Custody Deal: To secure Dela Rosa’s decisive vote, Cayetano immediately placed the former police chief under the “protective custody” of the Senate, declaring that the chamber would block any arrest orders unless they were explicitly issued by a domestic Philippine court.
The effort to replace Cayetano is being driven by sharp pushback from business leaders, legal experts, and fellow lawmakers who argue that the current leadership is compromising the institutional integrity of the Senate:
- The “Protective Custody” Backlash: Legal scholars and former lawmakers immediately called out Cayetano’s policy, labeling it a misreading of Republic Act No. 9851 and binding Supreme Court precedents regarding international treaty obligations.
- The Shootout and Public Backlash: Internal friction intensified following a dramatic exchange of gunfire inside the Senate building during the chaotic leadership transition, drawing widespread public condemnation.
- The Impeachment Dilemma: As the Catholic Bishops’ Conference of the Philippines (CBCP) and various civic groups demand an immediate, impartial trial for Vice President Sara Duterte, several majority senators are reportedly anxious that Cayetano’s overt protective actions toward the Duterte-Dela Rosa faction will undermine the credibility of the upcoming trial.
As the Senate prepares to transition into a full-scale judicial body, the numbers required to sustain a leadership challenge or secure an impeachment conviction remain tightly contested:

While Cayetano managed to gavel the session to order and officially issue the writ of summons to the Vice President, Senate insiders indicate that the numbers are in constant flux. With a minority bloc eager to reclaim control and a majority faction weighing the heavy political liabilities of shielding individuals from international courts, the leadership structure is expected to face continued stress in the coming weeks.
