Liberal Party (LP) senators were removed from key posts in the upper house of Congress on Monday, following the arrest and detention of their ally Leila de Lima last week for a drug case.
Senator Franklin Drilon was removed from his post as Senate President Pro-Tempore and replaced by Senator Ralph Recto after garnering 17 votes.
Several LP senators were also stripped of their committee chairmanships in the reorganization.
Senator Cynthia Villar of the Nacionalista Party (NP) took over as chair of the Agriculture and Food committee from LP Senator Francis Pangilinan.
Independent Senator Francis Escudero replaced LP Senator Bam Aquino as chairman of the Education Committee.
Senator JV Ejercito replaced Senator Risa Hontiveros as chair of the Committee on Health and Demography.
Aquino, Drilon, Hontiveros, and Pangilinan said they would join Senators De Lima and Antonio Trillanes in the minority.
