Singapore (AFP) - Thousands of people braved heavy rains Sunday to line major streets in Singapore for a final farewell to founding leader Lee Kuan Yew, who will receive a rare 21-gun salute before a state funeral attended by world dignitaries.Officials said more than 450,000 people had paid their last respects to the 91-year-old, who served as prime minister for 31 years, before his public wake ended in parliament on Saturday night."It has been a deeply moving experience," his son, Prime Minister Lee Hsien Loong, said in a Facebook post thanking the public for honouring the former leader, who died Monday after seven weeks in hospital.Families turned up early to catch choice spots along the 15-kilometre (10-mile) procession route from parliament to the National University of Singapore, where the state funeral will start at 2:00 pm (0600 GMT)."We are here today as a family to witness this historic moment.
