In 1997 Chris Patten walked away as the final British governor of Hong Kong in a symbol of Britain's continual imperial decline. Having taken the blame for Margaret Thatcher's hated poll tax, he was ousted as the Conservative MP for Bath in the 1992 general election and has been described by The Observer as 'the best Tory Prime Minister we never had'. His book, The Hong Kong Diaries has been published by Penguin to mark the 25th anniversary of the handover.
