DAVAO CITY - Presumptive President Rodrigo Duterte on Monday night gave dire warnings to supposedly corrupt and inefficient government agencies and officials.

Speaking to reporters in Davao City, Duterte called the Bureau of Internal Revenue (BIR), Bureau of Customs (BOC) and Land Transportation Office (LTO) as the "most corrupt" agencies.

Duterte also said it may be better to simply disband these agencies.

"I'm very sorry pero sabihin ko sa inyo, isa sa pinaka-corrupt na agency ang BIR, Customs, LTO -- iyang tatlong iyan... I-abolish ko na lang para wala na," he said.

Duterte also lambasted the "useless" Philippine Drug Enforcement Agency (PDEA), saying that it cannot combat illegal drugs because many of its own officials are embroiled in the narcotics trade.

He added that a high-ranking PDEA officer needs to be sacked from the agency because of alleged connivance with drug syndicates.

Duterte said that once he assumes office, he will order the military to take over the corruption-riddled agency.

Aside from the PDEA, Duterte also wants military men to lead the Bureau of Immigration (BI), and the Bureau of Corrections (BuCor), which maintains the New Bilibid Prison (NBP).

He also warned local government officials involved with illegal drugs. "Huwag kayong magkamali d'yan kung naaawa kayo sa sarili n'yo. P***** *** mamamatay kayo d'yan." -- With reports from Roxanne Arevalo and Doris Bigornia, ABS-CBN News
