GOVERNOR Chris Patten will cut short his visit to Europe next month in the expectation that he will have to return to Hong Kong quickly following a decision to go it alone on democratic reform. The Governor was due to spend five days in France, the Netherlands and Germany following talks with the Prime Minister, John Major, and Foreign Secretary Douglas Hurd, in London. But now Chief Secretary Designate Anson Chan Fang On-sang will take the latter stage of the trip while Mr Patten returns directly to Hong Kong. The decision to cut short Mr Patten's stay was taken in consultation with the Foreign Office following the failure of the 13 rounds of talks in Beijing so far and the likelihood that there would be little further progress in the 14th and final round. Mr Patten is expected to run through his options in talks with Mr Hurd and Mr Major during the five days after he arrives in London on November 8. Unless there is a breakthrough with China, an announcement on going ahead unilaterally and letting Legco decide on the future road for democracy for the territory is expected to be made later at a cabinet committee meeting on November 11. A Whitehall source said: ''They simply decided it would be better for Mr Patten to be free to return to Hong Kong rather than spend another week in Europe in case there is an announcement when he is here.'' Mr Patten will have a hectic week - besides the normal rounds of meetings with ministers, officials, MPs and others, he is to speak to the Hong Kong Trade Development Council's annual London dinner. The following day, he and Mr Major will be the keynote speakers at a conference entitled ''Hong Kong Works'' organised by the Hong Kong Government and the Institute of Directors. Other speakers include Lady Dunn; Sir William Purves, the group chairman of HSBC Holdings; Dr Victor Fung, the chairman of the Trade Development Council; and Peter Woo Kwong-ching, chairman of Wharf Holdings. Most of them will go on to mainland Europe with Mrs Chan to co-host a series of trade and investment seminars and conferences in Amsterdam, the Hague and Paris in what has been billed as Hong Kong's biggest ever promotion in Europe. A government spokesman in Hong Kong said: ''During his visit to London, Mr Patten will be holding discussions with the Prime Minister and the Foreign Secretary on the latest situation in the talks with the Chinese Government on electoral arrangements for the 1994/95 elections. ''The Governor has made it clear that we have only weeks remaining before important decisions have to be made on the arrangement for the 1994/95 elections. He therefore wishes to return to Hong Kong following his discussion in London.'' The spokesman said Mr Patten attached great importance to the Hong Kong promotion, which would provide European political leaders and businessmen with a better understanding of what was happening in Hong Kong, enhance Hong Kong-Europe links, and emphasise business opportunities for Europe in the territory. ''The Governor is delighted that Mrs Chan, our first local Chief Secretary, will carry the Hong Kong message to such important international audiences,'' he said. Mrs Chan is due in Britain later this month for familiarisation meetings with Mr Hurd and others before she takes up her post.
