Chi-Chi the Panda

Refused entry to America from China in 1958 because of the embargo on "communist goods", the giant panda Chi-Chi came to London Zoo - a constant object of media attention and public adoration. Eight years later she was sent on a diplomatic mission to Moscow to mate with the Russian panda An-An, though this attempt to start a thaw of the Cold War failed on day one when she hit An-An. Among those recalling this bizarre tale of sex, spies and the media are Desmond Morris, Sir Denis Forman and Edward Heath, who remembers his own brush with pandas when he was prime minister.
