Anti-Trident campaigners will hand in 40,000 signatures collected for a ‘Stop Trident’ petition to the Ministry of Defence at 12 noon today.

MPs are set to debate the replacement of Britain’s nuclear weapons system this afternoon and will vote at 10pm.

Anti-Trident campaigners will hold a protest outside Parliament from 6pm. MPs opposing the government motion to replace Trident are expected to address the rally.

Kate Hudson, CND general secretary, said:

“This is a once in a generation opportunity to break with this massively expensive yet redundant old technology and instead spend Britain’s valuable resources on meeting the security challenges we face today, like terrorism and climate change.

“We need our government and parliament to show the kind of vision and wisdom necessary in our rapidly changing political environment: to have the courage to abandon the totems of a bygone age and vote down these militarily useless weapons of destruction.”
