That this House notes that the UK is facing its biggest economic crisis since the Second World War and can ill afford to spend in excess of £76 billion on replacing the Trident nuclear weapons system; further notes that the UK's security needs are not met by nuclear weapons which do nothing to combat the threats posed by terrorism or climate change; further notes that while countries such as the UK justify their retention and replacement of nuclear weapons on the grounds of an uncertain future, the more likely it is that non-nuclear states will use the same rationale to justify developing their own weapons systems; and calls on the Government to cancel the replacement of Trident, to re-orientate the skilled manufacturing base towards the needs of a post-carbon future, making significant investment in green jobs and reallocating funds towards socially useful spending.
