Steered by his 1913 Bradshaw’s Guide, Michael Portillo embarks on a four-part rail adventure through Thailand from the northern city of Chiang Mai to Kanchanaburi on the River Kwai, and from Bangkok to the southern beach resort of Hua Hin. On this leg, Michael tries his hand at the art of umbrella making and learns about northern Thai cookery. He explores the walled and moated city of Chiang Mai, former capital of the Lanna Kingdom before it was annexed by the King of Siam. Travelling south to Lampang, Michael discovers the former centre of the teak wood business and investigates how successive Thai kings preserved their independence from the rival colonial powers of Britain and France. He discovers the history of a British governess at the royal court, who was made famous on stage and screen, and discovers how King George V kept elephants at the British Consulate.
