Politicians, military personnel and celebrities will come together today to highlight why replacing the Trident missile system is a dangerous and expensive distraction from the real threat facing our planet - climate change.
Ken Livingstone, Annie Lennox, Anita and Gordon Roddick, Bianca Jagger, Tony Robinson and Major General Sir Patrick Cordingly will be among those on Greenpeace's Arctic Sunrise ship to explain why they don't want the UK to spend up to £76bn on outdated, unnecessary and dangerous weapons of mass destruction.
