The former Philippine president Rodrigo Duterte accused his successor, Ferdinand Marcos Jr, of being a drug addict who risked being ousted from office in an expletive-laden tirade that underlined the breakdown in relations between the two powerful political families.

Duterte’s speech on Sunday, in which he claimed Marcos Jr’s allies were trying to remove constitutional term limits so they could cling to power, follows long-running speculation about hostilities between the families.
