Ferdinand Marcos Jr has been sworn in as the Philippine president in a ceremony in Manila, succeeding the outgoing leader Rodrigo Duterte. His inauguration marks a stunning comeback for the Marcos political dynasty, which was ousted after a popular revolt in 1986. Mr Marcos Jr - nicknamed Bongbong - won an election landslide last month. Sara Duterte, the daughter of the outgoing president, is being sworn in as vice-president.
