LAWYER, public relations company boss and socialite Ada Wong may be adding another string to her bow - that of Legislative Councillor. Ms Wong last week told P.S. she planned to stand in the 1995 elections as a member of the Liberal Party - ''if that is what they determine they want me to do''. ''It is very exciting, I think I finally know what I really want to do most, and now I have the chance,'' the 33-year-old said. Sixty seats will be contested during the poll, 20 by direct election, 30 through the functional constituencies and 10 to be decided by an electoral committee. Conscious of the criticism that none of their members have won a Legco election, Liberals such as Ms Wong are anxious for as many of their number to gain Legco seats through universal franchise. Ms Wong had no hesitation in saying she wanted to win a directly elected seat to earn her place in Legco. ''I think I want to get the mandate of the people. That is not to down play the role of the functional constituencies, because they were there to serve a purpose when Hong Kong people were apolitical.'' She also conceded her age would be a bar to her contesting the legal profession's Legco seat against well-known incumbent Simon Ip. Ms Wong joined her family's law firm after attending law school in England, but from 1989 she has also been the co-owner of the Occasions public relations firm, along with Stanley Ho's daughter, Pansy Hui. While she would probably bristle at the thought of being labelled a socialite, Ms Wong is frequently pictured in the social pages of Chinese and English-language magazines. As if that was not enough, she was also active in launching the Liberal Party, working with its best-known figures, Allan Lee Peng-fei and Selina Chow Liang Shuk-yee, on the start-up committee. Although the precise form of the elections remains a matter of intense diplomatic exchanges between Britain and China, it is clear the atmosphere will be rather more intense than during the 1991 polls - not least because the members are in theory to sit through the handover to the Chinese two years later. ''I am under no illusions about the difficulties I will be facing. I understand my weakness is that I have no experience, but I think politics is about motivating people, organisation and about trying to solve problems. And I think that my legal and public relations background will help me,'' said Ms Wong. She said the 1,100-member party was still in the early stages of selecting candidates and that its full list would not be known until Christmas.
