Singapore is holding nationwide events to mark 50 years since it became an independent state.
Tens of thousands of people are expected to attend an outdoor parade, complete with flybys by the air force and a Singapore Airlines A380 airliner.
Singaporeans are also being asked to join together in reciting the national pledge and singing the national anthem.
Singapore became independent when it was ejected from the Federation of Malaya amid social unrest.
In 50 years, the former British colony has transformed itself into one of the world’s wealthiest countries.
But its critics say the rapid development has been accompanied by a strict control on free speech and politics.
