The leader of a coup in Fiji, Commodore Frank Bainimarama, has been sworn in as interim prime minister, one month after overthrowing the government. Cmdr Bainimarama deposed prime minister Laisenia Qarase and named himself the country's president. However, Cmdr Bainimarama on Thursday returned executive authority to President Ratu Josefa Iloilo. An interim government is to be appointed and is expected to be dominated by the military. It will remain in power until elections. Mr Bainimarama said at a short swearing-in ceremony on Friday: "In all things, I will be a true and faithful prime minister." Mr Qarase remains banished on an outlying island.
