A mass wedding ceremony may be organised to celebrate the new millennium. The Hong Kong Catholic Marriage Advisory Council said it would consider holding the event after a similar ceremony was scheduled on the mainland. An estimated 1,000 couples will marry in Beijing on December 31 next year in the mainland's biggest mass wedding ceremony. Group weddings throughout the mainland are expected to attract more than 20,000 couples at the end of next year. Rita Chiu Lo Chi-pak, the marriage advisory council's executive secretary, said: 'It would be a good idea to have a mass wedding ceremony in Hong Kong to mark the new millennium - but we have not finalised any plans yet.' She said Grand Millennium Plaza near Sheung Wan MTR station would be an ideal venue. Meanwhile, the Immigration Department, which monitors marriage records, said it was watching the number of people applying to get married at the end of next year in case there was a flood of applicants. A spokesman said: 'We will keep a close watch.' He had no way of knowing at this stage how many marriages were planned for December 31 next year.
