Albert Cheng brands Lee Wing-tat crazy for calling him a double agent for Tsang A rift within the pro-democracy camp over Democratic Party chairman Lee Wing-tat's bid for the post of chief executive widened yesterday. Mr Lee duelled with Albert Cheng King-hon inside and outside the Legislative Council chamber, each calling the other 'stupid' and 'crazy'. Mr Cheng questioned Mr Lee's efforts at defending Hong Kong's autonomy. The party leader accused the maverick former broadcaster of currying favour with acting chief executive Donald Tsang Yam-kuen. During a debate on legislator Leung Kwok-hung's motion denouncing Beijing's interpretations of the Basic Law, Mr Lee predicted that history would be repeated and more interpretations would occur under the undemocratic political system. But Mr Cheng accused Mr Lee of not doing enough to protect Hong Kong's autonomy, something that was especially important since he was seeking nomination for the chief executive election. After further angry exchanges, Mr Cheng withdrew his accusation and even called Mr Lee 'my good brother'. But tensions boiled over later in the corridors when Mr Lee dismissed Mr Cheng's apology as 'just a show', and accused the former talk-show host of being a double agent working for Mr Tsang - who has yet to declare his candidacy. 'He kept shooting arrows at me and his dirty tricks are stupid, because he openly criticised me while privately calling me a brother. 'Again and again he attacked me with the intention of pleasing Donald [Tsang]. His stance in backing Donald is very clear,' Mr Lee said. Mr Cheng had earlier said he would not support Mr Lee contesting the post, and declined to take his place in a group picture to back the Democratic Party leader's campaign. Mr Lee cited reports that Mr Cheng was leading a campaign to turn party supporters in favour of Mr Tsang. Mr Cheng dismissed the charge. 'Lee Wing-tat is crazy. Of course I support Donald Tsang, but I oppose the undemocratic election,' he said. Pro-government lawmakers joined forces to vote down the motion expressing regret over the three interpretations of the Basic Law by Beijing since 1999. Five democrats, Mandy Tam Heung-man, Joseph Lee Kok-long, Andrew Cheng Kar-foo, Lau Chin-shek and Leung Yiu-chung, abstained. Lui Ming-wah, of the pro-government Alliance, questioned whether Legco should 'waste time' revisiting the binding decisions of the National People's Congress Standing Committee.
