Sir Sze-yuen Chung said it was unfair to accuse only him of changing camps.
He rejected criticism that he had switched from serving Britain to China in recent years.
Sir Sze-yuen said: 'When Tung Chee-hwa was both an Executive Councillor [of the Hong Kong British administration] and a vice-chairman of the Preparatory Committee, where were accusations of him shifting camps?' He queried the role of Executive Councillors Dame Rosanna Wong Yick-ming and Dr Raymond Ch'ien Kuo-fung, who have been appointed by Mr Tung to his post-handover executive council.
Sir Sze-yuen said: 'Now Anson Chan Fang On-sang and Donald Tsang Yam-kuen are the same. As civil servants, they have the right to say no [to Mr Tung's appointment] as well.' Sir Sze-yuen said there were four years between him stepping down as senior Executive Councillor in 1988 and becoming a China-appointed Hong Kong affairs adviser.
Although China labelled him 'a remnant of the past dynasty' and Britain regarded him as a 'lackey', he had been senior Executive Councillor of the Hong Kong British administration and was now convenor of the Special Administrative Region exco.
Sir Sze-yuen said: 'What is the point? I act according to my conscience and work for the people of Hong Kong.'
