UNITED NEWS INTERNATIONAL (UNI) — A lawyer who helped file charges against Philippine senator Leila de Lima has been appointed to an anti-corruption body.

Eduardo Bringas was the lawyer for two former National Bureau of Investigation officials who filed drug charges against De Lima last year.

The criminal complaint, filed with Bringas’ help, called De Lima the “mother of all drug lords.”

De Lima served as secretary of justice from 2010 to 2015.

During that time, De Lima is accused of allowing drug syndicates to operate in the New Bilibid Prison in exchange for money.

De Lima, who is currently in prison, denies the allegations.

On Wednesday, Feb. 7, Philippine President Rodrigo Duterte appointed Bringas as the executive director of the Presidential Anti-Corruption Commission.

News of the appointment was reported Friday.

The commission has the power to investigate corruption cases amongst all presidential appointees in the executive branch.
