Democratic Party legislator Lau Chin-shek vowed yesterday to remain critical of the Government despite Tung Chee-hwa's help in fulfilling his wish to visit his mother in Guangzhou. After a four-day stay in Guangzhou, Mr Lau dismissed claims the Chief Executive or Chief Secretary for Administration Anson Chan Fang On-sang had set any conditions for his visit. 'I look at yesterday, today and tomorrow in an equally pragmatic manner. When the occasion warrants criticism, I will continue to do so unreservedly. But I will point out the good points whenever I encounter them. I wouldn't change my stance for the sake of returning to the mainland,' said Mr Lau, who is also a standing committee member of the Hong Kong Alliance in Support of the Patriotic Democratic Movement in China. He said he did not think he owed Mr Tung a favour. Mr Lau, who sought help from Mr Tung and Mrs Chan before the Lunar New Year, said he had met the Chief Executive two or three times since then to express his eagerness to visit his mother, 93, who has heart disease. Speaking from Shanghai, Mr Tung gave credit to the mainland authorities, adding it was 'the relevant mainland departments' that had made the final decision. Asked whether he would assist other alliance members to obtain home-return permits, Mr Tung said: 'I think an overwhelming majority of legislators in Hong Kong can return to the mainland. For those who cannot yet enter, I suggest they get an objective understanding of the country's latest achievements.' Amid claims he had returned to Hong Kong before the anniversary of the June 4 massacre on Sunday to avoid controversy, Mr Lau said the decision was purely his own. He denied the Chief Executive's Office has asked him to keep a low profile during his visit. Nor were there any public security officers tailing him. Mr Lau said he would seek to meet Mrs Chan next week to discuss the chance of a long-term permit. 'I hope I will no longer need to apply on an occasion-by-occasion basis,' he said. But he described the visit, his first to the mainland for 11 years, as a 'good beginning', adding: 'At least on this occasion, I managed to embrace my mother and chat to her for real and she no longer needed to wait in front of the television to see me.' He thanked Mr Tung, Mrs Chan, Financial Secretary Donald Tsang Yam-kuen and Secretary for Justice Elsie Leung Oi-sie for their help. 'My visit gave her a huge boost,' Mr Lau said. However, he said his mother had expressed worries about his future, saying she hoped he would consider 'doing some business' instead of politics. Mr Lau, who has 15 brothers and sisters, said: 'I don't think I'll do that.' The scene yesterday when Mr Lau bid farewell to his mother was much calmer and less dramatic than the reunion on Monday. Mr Lau said he would have stayed longer had it not been for the swarm of photographers and journalists who had hounded him and his mother.
