Newcomer Fung Chi-kin, in his maiden speech in the legislature, yesterday urged the Financial Secretary not to be so frank. Sworn in on Wednesday to replace disgraced legislator Chim Pui-chung, Mr Fung said there was no need for Donald Tsang Yam-kuen to say the Government will not in the near future sell the shares it bought in August. 'Why does he have to be so frank?' he said. He praised the Government's intervention in the stock and futures markets, saying it was a 'brilliant and decisive move'. Mr Fung, who represents the financial services functional constituency, called on the administration to exercise more control over derivatives products. He also suggested creating a body to develop and co-ordinate financial policies and oversee the Securities and Futures Commission and the debt and foreign exchange markets.
