Answer
The ouster of Pantaleon Alvarez as Speaker of the House of Representatives in 2018 was a significant political event involving Sara Duterte. Duterte, the daughter of then-President Rodrigo Duterte, had been a vocal critic of Alvarez and played a key role in his removal. Her support for Alvarez's ouster was seen as a sign of her growing political influence and a challenge to her father's authority.
