Jung Chang and Peter Florence
Jung Chang settled in UK after going there to study as one of the first Chinese students who attend a university in the West. She wrote a personal memoir about Mao's legacy in China (Wild Swans), and then a biography of Mao with her husband after 12 years of research, getting the most valuable documents from Russian archives of what went on in that period.
The most shocking news was that the great famine of 1958-1961 was deliberate starvation of the people by sending grain to the Soviet Union and its satellites because Mao wanted arms; it was paid in grain to the extent of 7% of China's GDP at the time.
Bringing along her mother's tiny shoes, Ms Chang demonstrated how half the population of China for more than 1000 years had been subject to the torture of foot-binding, all for a theoretical standard of looking dainty and sexy.
Stalin backed Mao from the early 1920s, after gauging he was utterly ruthless, and therefore capable of bringing Communism to China. No one joined the Party because of Mao's charisma, of which he had little.
Peter Florence takes questions from the audience
Chang said she never met as many Mao enthusiasts anywhere in the world as in India. In the 50s, 60s, 70s, being pro-Mao was a condonable weakness; but being pro-Mao now is inexcusable ignorance.
