Chief Executive Tung Chee-hwa will pocket more than $4 million in June after serving his first five-year term. The Chief Executive's Office has confirmed Mr Tung will be entitled to a contract gratuity worth 25 per cent of his total basic salary during his appointment. The gratuity is in line with colonial arrangements for previous governors. Chris Patten left with about $2.7 million in 1997 after his five-year rule. As Mr Tung will almost certainly serve another term taking him to 2007, politicians and academics said the Government should have a retirement package and post-service regulations ready before his reappointment in July. Professor Lau Siu-kai, of Chinese University, said the future chief executive should be given a pension for life. 'This is to ensure that he or she would not have to be worried about his future living and engage in business activities that might lead to a conflict of interest.' He supported a package similar to that enjoyed by former presidents of the United States, including a free office, secretarial support, mailing services and bodyguards. 'Bodyguards will ensure the leader will not have to worry about any revenge for making tough decisions, such as cracking down on triads, during his term,' he said. Cyd Ho Sau-lan, of The Frontier, agreed that a pension should be given but doubted if the future chief executive deserved benefits like former US presidents. 'I don't think bodyguards would be necessary. After all, our leaders do not risk being assassinated by terrorists,' Ms Ho said. She called for tight rules restricting ex-leaders from taking up important political posts, particularly on the mainland. 'If the chief executive knows he will have a political future in Beijing, it is doubtful if he would place Hong Kong's interests above Beijing's,' she said. 'I think the chief executive should treat his appointment as an honour in life and be prepared to end his political career after stepping down.' But her view was challenged by political commentator Ivan Choy Chi-keung, who doubted local rules could bar an appointment in Beijing. Referring to the political scene in the US, the City University applied social studies lecturer said: 'This is like preventing George W. Bush from moving up from his Texas governorship to become the president.' He said former chief executives should exercise self-discipline to avoid being seen as running into conflicts of interest. Professor Lau said too many restrictions would deter politicians from contesting the top job in future, but he agreed that any activities taken up after leaving office should be strictly monitored to avoid infringement of public interests. A government spokesman said officials were studying whether the chief executive should be given pension benefits as well as face other restrictions after stepping down.
