Rodrigo Duterte delivers his sixth and final state of the nation address before lawmakers on Monday but the controversial president of the Philippines appears in no rush to bow out. Momentum is building for Duterte to run for the vice-presidency in next year's elections, circumventing constitutional term limits by joining a family ticket headed by his daughter, Sara. Double Duterte could be a winning combination with voters, according to a recent opinion poll. But the proposal has split the ruling PDP-Laban party into two factions, pitting Duterte against senator Manny Pacquiao (pictured), a boxer and former loyalist who harbours his own presidential ambitions. Duterte's camp landed a heavy blow this weekend, ousting Pacquiao as party leader and installing a Duterte supporter in his stead. "Pacman", as Pacquiao is affectionately known, is currently in the US preparing for a world title fight against Errol Spence; a win against the highly rated American fighter might help to get his presidential ambitions off the ropes.
