Thousands of Thai mourners are lining the streets of Bangkok, hoping to see the body of King Bhumibol Adulyadej as it it moved from a hospital to a temple in the Grand Palace.
The world's longest-reigning monarch died on Thursday aged 88, sparking a national outpouring of grief.
The government has declared a year-long official mourning period.
Crown Prince Maha Vajiralongkorn has been named as successor, but has asked for a delay in the process.
The cabinet has declared Friday a government holiday, and flags are to fly at half-mast for the next 30 days.
People have been asked to wear black, and avoid "joyful events" during this period. Cinema screenings, concerts and sports events have been cancelled or postponed.
News websites have turned their pages black and white, and all television channels in Thailand are airing programmes about the king's life.
"This is the worst loss in my life," said one of those lining the streets.
"I am confident that what he did for us improved our lives," said another.
"What we are doing now [waiting on the streets], is nothing compared to what he did for us."
