Sri Lanka's former president Mahinda Rajapaksa was sworn in on Sunday as the country's new prime minister at a historic Buddhist temple, days after his party won a landslide victory in the General Election. The 74-year-old Sri Lanka People's Party (SLPP) leader was administered the oath of office for the ninth Parliament by his younger brother and President Gotabaya Rajapaksa at the sacred Rajamaha Viharaya in Kelaniya, a north Colombo suburb.
