Hong Kong's government is showing disrespect to the public by staying silent over Tung Chee-hwa's future, Catholic Bishop Joseph Zen Ze-kiun said as the main political parties stepped up their demands for the chief executive to reveal whether he plans to resign. 'It is so chaotic. It is taking so long. There have been so many rumours and nobody is coming out to clarify the situation. This is showing disrespect to Hong Kong people,' the bishop said. Bishop Zen, who earlier said Mr Tung's successor should be a 'mediator' who could fight for Hong Kong's interests rather than just serving as the central government's spokesman, said regardless of whether it was Mr Tung's or Beijing's decision, the public should be told the truth. 'We should be told what has happened. We have the right to know.' Bishop Zen also said that, as he understood it, the Basic Law stated that Mr Tung's successor should serve a five-year term. Both the Democratic Party and Liberal Party said the government should immediately clarify whether Mr Tung plans to resign. Lee Wing-tat, chairman of the Democrats, said he had written to Mr Tung demanding a meeting. Executive Councillor Selina Chow Liang Shuk-yee, of the Liberal Party, also said it was 'far from ideal' that the public was being kept in the dark.
