Citybus has refused to rent a double-decker to organisers of the city's first gay parade tomorrow because of concerns over its 'company image'.
Gay rights activists have condemned the bus company's decision as discriminatory and a legislator and the government have asked Citybus to clarify its position.
As many as 1,000 people are expected to participate in tomorrow's Pride Parade 2008, the first large-scale gay carnival and procession in the city.
The organisers approached Citybus last Friday, planning to rent an open double-decker for the parade, which will see the participants march from Causeway Bay to Wan Chai.
Li Chun-wai, a spokesman for the organisers, said negotiations had seemed smooth until Wednesday, when the bus company wrote to reject their application.
In an e-mail, made public yesterday by Mr Li's group, the company said it would not discriminate against any party: 'When our company makes a commercial decision, we shall consider various factors, including the image of our company.'
