Chief Secretary Donald Tsang Yam-kuen is set to take legal action against a magazine over an allegedly libellous article. A spokesman for Mr Tsang said the article, published two weeks ago in Eastweek, contained a number of completely 'false and groundless' claims against Mr Tsang. Mr Tsang, who under Civil Service Regulations is entitled to legal assistance, had chosen to meet his own legal expenses, the spokesman added. It is understood Mr Tsang's lawyer has written to the magazine demanding an apology within three days, or the matter will be taken to court. Eastweek was unavailable for comment yesterday. The article quoted Mr Tsang's former chef, Yu Yin-ping, and mentioned Mr Yu's intention to write a book on his days working in the then-financial secretary's official residence in Shouson Hill Road, Wong Chuk Hang. Mr Yu began working for Mr Tsang as head chef in December 1999, but his contract was terminated in October last year. Last June, Mr Yu was awarded $40,250 in outstanding overtime pay by the Labour Tribunal.
