COLOMBO, Sri Lanka (AP) — Sri Lanka will hold its presidential election on Sept. 21 in a crucial vote that will decide the future of the South Asian nation still struggling to recover from its economic collapse in 2022, which provoked mass protests and forced the former President Gotabaya Rajapaksa to flee the country and later resign. The election is seen as a referendum on President Ranil Wickremesinghe's two-year-long rule that has overseen a fragile recovery of the country's economy. He faces a tough challenge from the leader of the opposition in parliament, as well as from a left-leaning politician with a powerful alliance, who is gaining popularity among young voters.
