Three years ago, the most powerful political families in the Philippines joined hands to secure the nation's biggest election victory in four decades. Now they are locked in a feud that threatens to derail one of Asia's economic growth stars.

Rodrigo Duterte previously insisted that the ICC has no jurisdiction over the Philippines, since he pulled the country out of the tribunal in 2019, three years after it took note of the drug war's rising death toll.

The police custody of former Philippine president Rodrigo Duterte upon an arrest warrant issued by the International Criminal Court (ICC) against him has again exposed the growing rift between two of the country's most influential political dynasties, analysts said.
