Lawmakers are seeking an explanation from the government for the reported use by Chief Executive's Office director Norman Chan Tak-lam of a public relations firm run by an election aide to Donald Tsang Yam-kuen. Democratic Party lawmaker Cheung Man-kwong yesterday wrote to Chief Secretary Henry Tang Ying-yen expressing concern that Mr Chan may have deviated from proper administrative procedures. A media report on Monday said Mr Chan had arranged lunch meetings with senior executives of media organisations last month through Suki Yau Suk-yee, a co-managing director of corporate communications consultant firm Citigate Dewe Rogerson. Ms Yau served on Mr Tsang's campaign team for his 2005 election and 2007 re-election. Apple Daily reported that she was present in gatherings she arranged for Mr Chan. 'Why did Mr Chan skip existing government procedures, bypass staff at his own office, the information co-ordinator and the Information Services Department to make the invitations?' Mr Cheung asked in his letter. The legislator later said government communication through a private company could lead to confidentiality concerns, and criticised Mr Chan for lacking political sensitivity. 'When you're in a position as high as him, you have to do everything by the book,' said Mr Cheung. 'There should be no conflict of interest. But here, the government seems to be giving an interest to this company.' A spokeswoman for the Chief Executive's Office said: 'Neither the Chief Executive's Office nor the director has hired any companies or individuals to provide public relations or media services. The director had lunches with people from different sectors from time to time.' Ms Yau said yesterday that she and Mr Chan had lunched with a media practitioner in the middle of last year. She said it was just a social occasion. Civic Party leader Audrey Eu Yuet-mee said she would not jump to conclusions, but since the public was concerned, Mr Chan should explain. Ip Kwok-him, of the Democratic Alliance for the Betterment and Progress of Hong Kong, did not see much of a problem if Ms Yau had been present in a private capacity. 'But if she was there on behalf of the government, I would want to know why the government did not use the Information Services Department,' he said. However, League of Social Democrats chairman Wong Yuk-man said: 'If the public knows, then it's not private is it?'
