Mike Hancock, the MP for Portsmouth South, was at the city's rally today. He was there to support demonstrators hoping to save 940 BAE jobs. The cuts were announced earlier this week.
1800 jobs will be cut in shipyards operated by BAE Systems across England and Wales, bringing shipbuilding in Portsmouth to an end.
Unions are to meet defence giant BAe Systems to discuss the future of the firm's three shipyards amid a review of its business.
