Sen. Sherwin "Win" Gatchalian was formally elected Senate President at the June 17 special session called by President Marcos, ending a five-week leadership war after Sen. Joel Villanueva joined the majority to give it the 13 votes it had lacked — and after Alan Peter Cayetano, an hour before the vote, conceded the new bloc had the numbers.
MANILA — Senator Sherwin "Win" Gatchalian was elected Senate President during a special session of Congress on Wednesday, June 17, 2026, sealing a leadership change that had paralyzed the chamber for more than five weeks. According to the Philippine Daily Inquirer, all 13 senators present voted for Gatchalian after Senator Joel Villanueva crossed over to join the 12-member majority bloc, finally delivering the simple majority the Constitution requires to install a Senate President.
The vote resolved a deadlock that began on June 3, when 12 senators elected Gatchalian as acting Senate President and Senate President pro tempore but fell one vote short of the 13 needed to formally unseat Cayetano. Cayetano, who had assumed the presidency on May 11, refused for two weeks to recognize that he had been ousted, leaving the Senate with two men claiming the same gavel.
Cayetano concedes hours before the vote
About an hour before the special session convened, Cayetano announced he was giving up his claim to the presidency after Villanueva informed him he would back Gatchalian. "Alan Cayetano concedes Gatchalian camp has numbers," the Inquirer reported, citing the senator's own statement. The concession ended a standoff Cayetano's bloc had escalated only a day earlier by asking the Supreme Court to nullify the June 3 session as lacking a valid quorum.
Gatchalian is the fourth Senate President of the 20th Congress, succeeding Cayetano. The new majority, per the Inquirer, comprises Gatchalian, Villanueva, Majority Leader Migz Zubiri, and Senators Vicente "Tito" Sotto III, Panfilo "Ping" Lacson, Risa Hontiveros, Francis Pangilinan, Bam Aquino, JV Ejercito, Francis "Chiz" Escudero, Raffy Tulfo, Erwin Tulfo, and Lito Lapid. Sotto was elected Senate President pro tempore.
The minority bloc aligned with Cayetano includes his sister, Senator Pia Cayetano, along with Senators Loren Legarda, Imee Marcos, Rodante Marcoleta, Camille Villar, Mark Villar, Robin Padilla, Christopher "Bong" Go, the detained Jinggoy Estrada, and the fugitive Ronald "Bato" dela Rosa. GMA News Online reported that the Cayetano bloc, after snubbing the morning vote, returned to the floor in the afternoon and ultimately accepted the new leadership, though not without a heated exchange between Pia Cayetano and Hontiveros.
A session Marcos called for bills — and that settled the Senate
President Ferdinand Marcos Jr. summoned Congress to the special session under Proclamation 1318, asking lawmakers to "urgently consider" eight priority measures and to let the Commission on Appointments act on pending appointments that had been stalled by the leadership fight. According to the Philippine News Agency, the Commission on Appointments — chaired ex officio by the Senate President — confirmed five Armed Forces of the Philippines generals and 85 Department of Foreign Affairs officials the same day, after waiving the customary five-day notice requirement and declaring a quorum with 22 members present.
The leadership resolution carries immediate consequences for the impeachment trial of Vice President Sara Duterte, set to begin July 6. Philstar reported that the majority has tentatively agreed to elect Escudero — whose June 3 defection helped trigger the takeover — as presiding officer of the impeachment court, rather than Gatchalian, who is not a lawyer.
Context
The five-week crisis was the most protracted Senate leadership dispute in recent memory, consuming session days the executive needed for an anti-dynasty bill, a supplemental budget, and military confirmations. It unfolded against the backdrop of the multibillion-peso flood control corruption scandal, which has implicated several senators and shaped the chamber's shifting alliances. Villanueva himself faces an Office of the Ombudsman probe over Bulacan flood control projects even as his vote proved decisive; Estrada, a Cayetano ally, was placed under a 90-day preventive suspension and remains detained on plunder charges tied to the same scandal.
The Supreme Court had earlier declined to referee the dispute. On June 10 it dismissed a petition by a high school teacher seeking to validate the June 3 session for lack of legal standing, leaving the leadership question to be settled by the senators themselves — which is ultimately what happened on the floor on June 17.
