GOVERNOR Chris Patten, seen by some in the West as a democracy crusader, will come under fire from Martin Lee Chu-ming during the liberal legislator's tour of the United States and Canada. Speaking before leaving yesterday for the 18-day trip, Mr Lee said he would tell officials and the media that he was not happy with the concessions made by London over the 1994/95 electoral arrangements. Mr Lee will meet Canada's Secretary of State (Asia Pacific), Raymond Chan, in Ottawa, and the US Acting Secretary of State, Peter Tarnoff, in Washington DC. The United Democrats chairman will also lecture about Hong Kong's recent political development. ''I will tell them that I am extremely disappointed about the two major concessions made by the Governor this summer. I just cannot see how they can find 31 out of the 60 legislators to say 'no' to Beijing on crucial matters,'' Mr Lee said.
