WATCH: Arroyo takes oath as new Speaker in House coup

Pampanga Congresswoman and former President Gloria Macapagal Arroyo has taken over as the new Speaker of the House of Representatives Monday afternoon, ousting Speaker Pantaleon Alvarez ahead of the third State of the Nation Address. 

Video of the proceedings at the Batasang Pambansa plenary hall showed Arroyo climbing the rostrum with Rep. Fredenil Castro and taking her oath while being flanked by several lawmakers from Central Luzon. 

She then spoke into the mic despite the sound system being turned off as lawmakers applauded. At one point, Mrs. Arroyo had to shout so that she could be heard by the people. 

A DZMM report said Rep. Karlo Nograles called out the roll call for the vote on the new Speaker. 

Arroyo, who sat as President from 2001 to 2010, is the first female Speaker of the Lower Chamber. 

Multiple sources earlier said Arroyo was being pushed by the majority to replace Alvarez, who had been at odds with the President's daughter, Davao City Mayor Sara Duterte-Carpio.
