Is the most closely guarded secret of 1997 - the guest list for the midnight handover ceremony - out of the bag? A mystery file listing more than 2,000 VIPs landed in the South China Morning Post computer system, apparently from the Government Information Services (GIS). It is bursting with dignitaries rumoured to have been invited to the June 30 bash, including British MPs, former American president George Bush, veteran US statesman Dr Henry Kissinger, a few former Japanese prime ministers . . . and the Archbishop of Canterbury, Dr George Carey. Even French President Jacques Chirac, Canadian Prime Minister Jean Chretien and Japanese premier Ryutaro Hashimoto, not invited because they are too senior, are there. This could be a sign that it is simply a guest wish list . . . or even the Governor's farewell card list. But just where it came from remains a mystery. The Government last night denied any knowledge of the list. A GIS spokesman said technicians had not sent it out during a testing session on Saturday afternoon. Handover ceremony co-ordination office spokesman Jonathan Lange insisted: 'It's not the handover guest list and not associated with it.'
