SENIOR Executive Councillor Lady Dunn yesterday said there would not be an indefinite delay in tabling the 1994/95 electoral bill in the Legislative Council. Speaking after an Executive Council meeting, Lady Dunn said: ''I think an indefinite postponement of the bill is not an option, given that we have to have electoral provisions in place before the 1994 and 1995 elections.'' She reiterated that a decision on when to put the electoral bill to Legco would be made after Easter. She said she was glad to hear from some Hongkong affairs advisers that Beijing had taken a positive attitude towards the resumption of Sino-British talks on political reform. However, a vice-director of the local branch of the New China News Agency, Mr Zhang Junsheng, yesterday said: ''The ball is in the British court.'' Quoting Chinese Prime Minister Mr Li Peng's earlier remark that ''the one who tied the knot should be the one to untie it'', Mr Zhang said it was the British side who had destroyed the basis for talks. Meanwhile, more than 130 members of the 19 district boards called for the resumption of Sino-British talks to solve the political controversy on the territory's future. Nine representatives of the district board members handed in a joint statement to Government House yesterday. The statement, signed by 131, or one-third, of all district board members, said that only through Sino-British negotiations could the political controversy be solved and the prosperity and stability of Hongkong preserved. They urged the Government not to table the electoral bill in Legco and not to insist on having Hongkong Government officials as full members of the British negotiating team. A spokesman, Mr Wong Chi-keung, said copies of the statement would be given to the British Prime Minister, Mr John Major, Foreign and Commonwealth Affairs Secretary Mr Douglas Hurd and parliamentarians through the Hongkong Government's office in London.
