Lau Chin-shek was censured by the Democratic Party yesterday for failing to vote against the 1997-98 transitional Budget. Vice-chairman Anthony Cheung Bing-leung said that after several hearings the disciplinary committee ruled last week that Mr Lau had breached party discipline. Mr Cheung admitted some members were 'unhappy' with Mr Lau's disobedience, but he said it would not affect Mr Lau's relationship with the party. 'The most important thing is that Mr Lau admitted he was wrong, and the penalty is already very mild,' Mr Cheung said. Mr Lau, chairman of the Confederation of Trade Unions, abstained when the party voted against the 1997-98 Budget because the Government failed to raise the Comprehensive Social Security Assistance payment for the elderly by $300. Mr Lau said yesterday he had asked the party for an exemption, but it was rejected. A founding member of The Frontier grouping, he admitted differences with the Democratic Party. But he denied he was discontent with the party's radical practices and said he would not quit it. 'I am willing to face the penalty,' he said. Mr Lau has had his differences with his party and the Government. When the Democratic Party supported a freeze in government fees in 1995 to curb inflation, he only supported a freeze in charges related to livelihood. When the party supported a motion debate moved by James Tien Pei-chun of the Liberal Party to reduce the profits tax rate, Mr Lau opposed it.
