Thailand came to a standstill on Friday as a crowd of a million well-wishers flocked to Bangkok's Royal Plaza to celebrate the diamond jubilee of the country's much-loved monarch. Millions more watched on their TV sets as 78-year-old King Bhumibol, clad in an ornate golden coat, addressed the nation 60 years after his coronation.
Queen Sirikit was by the sovereign's side as he appealed for national unity, telling his subjects they should "synchronise their thoughts, minds and behaviour for the good of the Thailand".
An outpouring of enthusiasm greeted what was his first public audience in six years, with many Thais turning out in yellow, traditionally the colour worn to mark his birthday.
Festivities will include a gala dinner to be attended by royals from 25 nations, including Britain's Prince Andrew, as well as a spectacular royal barge procession and the release of 25,000 prisoners.
The world's longest reigning monarch, King Bhumibol is deeply revered in the Asian nation. Since ascending the throne at the age of 18 he has seen more than 20 prime ministers, 16 constitutions and 17 coups.
A passionate environmentalist, the king has travelled the length of Thailand, visiting the poorest regions and introducing countless projects to improve the conditions of the rural workers.
The Thai media also highlights his thriftiness, pointing to his reputation for never throwing away half-used pencils and adopting street animals as pets. One of his dogs, Copper, has even been the subject of an educational comic book, penned by the king about her adventures.
