Philippines' Duterte a controversial anti-establishment firebrand

To his critics, Rodrigo Duterte is a foul-mouthed, serial adulterer fixated on killing criminals. Duterte, 71, was sworn in on Thursday as the 16th president of the Philippines after a controversial but wildly successful election campaign dominated by his vows to kill tens of thousands of criminals and tirades against the nation's elite. Duterte rose to the nation's top job after spending most of the past two decades as mayor of Davao, the biggest city in Mindanao, earning a reputation as a ruthless leader willing to forsake human rights to enforce law-and-order.
