Former Philippine President Rodrigo Duterte was almost certain to be elected mayor of his home city by a landslide on Monday, unimpeded by his detention at the International Criminal Court on charges of murder as a crime against humanity.

Nicknamed "the Punisher" and "Dirty Harry", Duterte served as Davao's mayor for two decades before becoming president. Now he has been reelected despite facing charges linked to a brutal war on illegal drugs.
