MANILA - Another high-ranking official of the National Historical Commission of the Philippines (NHCP) resigned from his post in protest of the burial of the late strongman Ferdinand Marcos in the Libingan ng mga Bayani or Heroes' Cemetery.

Commissioner Francis A. Gealogo, Ph.D posted a photo of his resignation letter addressed to President Rodrigo Duterte Tuesday, after NHCP chair Maria Serena Diokno announced her resignation.

The letter, dated November 19, was submitted to the president a day after Marcos was buried at the heroes' cemetery.

In his letter, Gealogo reaffirmed the Commission's opposition of the burial, adding that it was based on "solid historical research."

"I believe that the Commission's stand opposing the burial of Ferdinand E. Marcos Sr. at the Libingan ng mga Bayani is based on solid historical research and is made as part of the mandate of the Commission to clarify issues pertinent to historical questions that confront our society," he wrote.

"I stand by the historical truth of the fact that the martyrs and victims of martial law should be the ones that we ought to recognize as the true heroes of our nation, and not the dictator who caused untold miseries and suffering to our people," Gealogo added.

Gealogo said he waited for Diokno to tender her resignation before making his own announcement.

Aside from sitting as a member of the board of NHCP, Gealogo is also an associate professor of history at the Ateneo de Manila University.
