The Professional Teachers' Union will nominate its president, Democrat Cheung Man-kwong, to run again for the education constituency in September's election. The nomination was supported by an overwhelming majority of union members. Mr Cheung has represented the constituency since 1991 after former president Szeto Wah opted to enter geographical elections. The union polled its 75,000 members, who represent most of the constituency's voters, after its decision last month to nominate Mr Cheung. Of the 14,947 members who replied, 85 per cent supported the nomination, about three per cent were opposed and 12 per cent had no comment. A union spokeswoman said no one stood against Mr Cheung at last month's executive committee meeting. 'Mr Cheung used to be the only nominee, the only exception was in 1991 when there were three candidates contesting the nomination. 'There is practical concern in putting the nomination decision before consultation. The teachers have their summer holidays in July so we are in a rush to have things settled.'
