In his speech, Sotto vowed to pass more laws for the benefit of Filipinos.

"I hereby pledge to continue in helping in the passage of laws that will be beneficial to the country and to every Filipino and to continue as well the diligence and dedication of Sen. Koko Pimentel who has been the principal author and sponsor of many landmark laws," he said.

He also thanked his fellow senators for trusting him with the chamber's leadership.

"I am deeply humbled and sincerely grateful to the Almighty God and to my fellow senators who reposed their trust and confidence in me and my capability to lead this august chamber at this critical and challenging time," he said.

Sotto, meanwhile, has campaigned against illegal drugs since he entered first politics as vice mayor of Quezon City in 1998, during the height of his career as an actor and musician.

As vice mayor, Sotto founded and organized the Quezon City Anti–Drug Council, which had been replicated in many local government units, according to his profile on the Senate website.

In 1992, Sotto began his 2-decade Senate stint, during which he served as minority and majority floor leader.

He also chaired the Senate committee on illegal drugs and led the Dangerous Drug Board as chair from July 2008 to November 2009. - with a report from RG Cruz, ABS-CBN News
