Secret Tiananmen memoirs revealed

The memoirs of China's former communist leader who was sacked after the Tiananmen protests have been published.

Zhao Ziyang's book lifts the lid on discussions within the party that led to the brutal crushing of the protest movement.

The publication of the book comes just weeks before the 20th anniversary of the killings.

The book is believed to have been based on secret tapes recorded while Mr Zhao, the party's former general secretary, was under house arrest.
