Gordon Siu Kwing-chue, new head of the Central Policy Unit, vowed last night to seek wide imput in formulating policy. He said it would be meaningless if civil servants were to dominate in the work of the government think-tank. Mr Siu said he expected the majority of members to come from the private sector. 'It is very important to maintain a balanced and mixed composition. And definitely, we will be as wide and cross-sectional as possible with the community,' he said. The unit, formed in 1989, was then headed by former journalist Leo Goodstadt and comprised a deputy from the civil service and three other full-time members seconded from the private sector. Mr Siu, who takes up the post next week, said it was too early to say whether there would be any changes. He denied speculation the unit had been at odds with policy secretaries. Secretary for Civil Service Lam Woon-kwong said: 'As a civil servant, I see no reason why senior civil servants are unable to develop wide contacts, raise new ideas and strategic thinking on policies.' But Democratic Party vice-chairman and academic Dr Anthony Cheung Bing-leung said the new appointment showed the focus of the unit might shift towards input from the civil service. 'This will be quite different from the time when it was set up to absorb the opinions from the private sector. 'It might become another bureau, say, policy co-ordination bureau, and no longer a think-tank. 'People will say there will be less new thoughts because civil servants are like-minded bureaucrats and tend to be more conservative. Mr Cheung, who has studied the civil service system, said the new appointment might show the strengthening of the influence of policy secretaries in the policy-making process.
