GOVERNOR Mr Chris Patten admitted his democracy blueprint could be altered by the Beijing talks. ''If the talks produce results which in our view would produce fair and open and acceptable arrangements for the elections then we could alter the arrangements that we have suggested so far.'' But Mr Patten added that the British team would not reach an agreement which it did not feel was acceptable in Hongkong. Mr Patten spent most of yesterday in talks at the Foreign Office after an audience with the Queen. Mrs Lavender Patten joined the Governor for his meeting with the Queen at Windsor Castle. The Governor denied there would be any differences between members of the team. That followed suggestions that the Foreign Office was more likely to accept China's view than Mr Patten or the Hongkong Government would. ''I am absolutely sure that all the members of the Government will work for a policy which is the policy of Her Majesty's Government,'' he said. There would be no divisions at the negotiating table between those from London and those from Hongkong.
