Franklin Magtunao Drilon (Tagalog pronunciation: [dɾiˈlɔn]; born November 28, 1945) is a Filipino lawyer and former politician.

[2] He had the longest tenure in the Senate of the Philippines (tied with Lorenzo Tañada and Tito Sotto), having served four non-consecutive terms overall: from 1995 to 2007 and 2010 to 2022.

Drilon was born and raised in Iloilo City and studied law at the University of the Philippines.

He moved to Angara, Abello, Concepcion, Regala & Cruz Law Offices[5] (ACCRALaw) in 1974, where he still serves as Senior Counsel.

Drilon served the government and public corporations through the following positions: As Justice Secretary, Drilon was instrumental in the prosecution and conviction of Mayor Antonio Sanchez of Calauan, Laguna, who masterminded the rape-slaying of a UP Los Baños coed and the murder of his friend; and Claudio Teehankee Jr., who was figured in the gun slaying of Maureen Hultman.

In 1998, he bolted Lakas and joined the Laban ng Makabayang Masang Pilipino (LAMMP) and supported Joseph Estrada in the presidency contest.

When Marcelo Fernan died of cancer the same year, he made concessions with Blas Ople in sharing the seat of the Senate President.

During the January 13, 2001, session of the impeachment proceedings, he was one of those who voted in favor of the opening of a mysterious second bank envelope.

Joseph Estrada was subsequently ousted that very evening by what would be remembered as the second EDSA People Power Revolution.

Drilon allowed Pimentel to occupy the Senate presidency until the end of the regular session in June 2001.

In 2003, administration coalition partner Liberal Party, to which President Arroyo's father, Diosdado Macapagal, served as chairman in the 1960s, invited Drilon to be its member.

That relationship ended on July 8, however, when Drilon---together with Biazon and some prominent members of the Liberal Party---decided to withdraw their support for her and asked for her resignation.

264, which prohibited members of the Cabinet from attending hearings of Congress, the Senate in particular, without permission from the President; he also opposed Proclamation No.

The lineup was carefully chosen and the first letter of the candidate's surname (except for Roberto Pagdanganan) ended up with the line VOT FOR D CHAMMP.

On 2012, after Senator Ralph Recto stepped down as the Chairman of the Senate Committee on Ways and Means, Drilon as its vice-chairman took over as its new chairman and worked firmly for the enactment of the Sin Tax Law that would impose higher taxes on the cigarettes and liquors.

[6] Drilon was married to fellow lawyer and ACCRA senior partner Violeta Calvo, with whom he had two children, Eliza and Patrick.

Central Philippine University bestowed upon him an honorary degree of Doctor of Humanities (Honoris Causa).
