Two or three non-civil servants will be chosen by Chief Executive Tung Chee-hwa to become policy ministers after the ministerial system is introduced in July. Informed sources say Mr Tung will also name another two or three people from the private sector to sit on the new Executive Council. One line of thinking is that this group should include a top lawyer and a leading banker. At present, there are three ex-officio members - the Chief Secretary, the Financial Secretary and the Secretary for Justice - and nine non-official members in Exco. But the new Exco is expected to have a membership of 12, including Mr Tung. It is envisioned that most of the existing non-civil servant members of Exco will be replaced by the politically appointed ministers. Between five and seven incumbent policy secretaries are expected to leave the civil service to become ministers. The source said: 'In the new Exco, it is likely that there will be two to three non-official members who do not necessarily have a specific policy portfolio. It is important to have some expert views in Exco discussion, such as a lawyer and a banker.' Mr Tung said at the end of a visit to Beijing early this month his priority task was the new accountability system. In last October's Policy Address, he announced the new system would be introduced in July. However, it has been learned that Mr Tung has yet to give a full briefing on his thoughts and details of the new system to his present team of policy secretaries. Also, individual officials have not been approached by him about political appointments. 'I think he has assumed senior officials have been briefed,' said a senior official, referring to a brainstorming session with 19 senior officials in July last year. Another source said there was a sense of anxiety among the top tier of the Government over the lack of details about the new system and its potential impact on the civil service system. The important question of powers and responsibilities between politically accountable officials and civil servants remained unclear, the source said. 'Senior officials are not worried about the inclusion of non-civil servants in the team. They will not resist outsiders as long as they are capable people and understand the issues well,' the source said. The first source said Mr Tung had kept his cards close to his chest regarding the list of appointees. However, he dismissed fears about difficulties for civil servants in switching to new roles as politicians. 'The new form of appointment will make a lot of difference. Civil servants will understand and adapt well to their new role . . . Furthermore, the senior echelon of civil servants will also become more politicised in future.' He said the Government would soon announce details of the ministerial system and seek funding from legislators for the new ministers' salaries and for the creation of new posts for the ministers' offices. 'Under the present economic situation, the public may not accept a major increase in pay for these politically accountable officials,' said the source, hinting the level would be only slightly higher than that of policy secretaries.
