Philippines' Pacquiao to fight drugs 'the right way' if elected president

Philippines boxing icon and presidential candidate Manny Pacquiao said he will welcome an international probe into President Rodrigo Duterte's bloody war on drugs if elected, and promised to fight narcotics "the right way", with due process, not street shootings.

In remarks this week to foreign journalists, Pacquiao, a former multi-division world boxing champion and once a staunch ally of the president, said he would be open to rejoining the International Criminal Court (ICC), which Duterte unilaterally withdrew the Philippines from in 2018.

Pacman, as he is known in the Philippines, is however trailing in opinion polls ahead of the May election, more than 50 points adrift of frontrunner Ferdinand Marcos Jr.

Duterte's presidency has been defined by his war on drugs, during which thousands of alleged dealers have been killed.

Rights groups and critics say law enforcers have summarily executed drug suspects, but police say those killed were armed and had violently resisted arrest.

Pacquiao, 43, has sought to set himself apart from Duterte, saying he will "continue the war on illegal drugs in the right way", with suspects given a fair trial and rehabilitated.

"When I said the right way, we will not kill them in the streets," he said on Monday.

"They will be given the right to defend themselves in court."

Duterte caused international outrage with his war on drugs and has dared the ICC to investigate him for crimes against humanity.

He has maintained those killed were all dealers who had violently resisted arrest and has publicly encouraged police to shoot suspects in self-defence, and said he would pardon those jailed for the killings.

The president's office did not respond to requests for comment on Pacquiao's remarks.

A former ship stowaway who learned to box in a Manila slum, Pacquiao also said he is certain lower-income voters will turn out in force to elect him.
