MANILA: Philippine President Rodrigo Duterte lashed out at vice-president Leni Robredo, a key critic of his government's crackdown on illegal drugs, on Tuesday (Jan 7), calling her a "colossal blunder.”

Duterte made the comments a day after Robredo said the country's anti-drug campaign has been a "massive failure” in constricting the supply of narcotics in the country in the past three and a half years.
