With MPs due to vote today on the future of Britain's Trident nuclear weapons programme, Kate Hudson from the Campaign for Nuclear Disarmament (CND) has told talkRADIO that the country could set an example to the world by re-purposing the £205 billion the programme will cost.
Prime Minister Theresa May has said it would be a "gross irresponsibility" to remove nuclear weapons from Britain's defences, adding, "the nuclear threat has not gone away. If anything, it has increased."
But Hudson, CND's general secretary, told Julia Hartley-Brewer that the huge sums of money involved could simply be better spent.
"Trident’s lifetime costs will total around about £205 billion, according to parliamentary figures," she said.
"So the question is: is this good use of our money to secure Britain’s defence?
"This decision is going to affect Britain's security for decades to come.
"The money that is spent on Trident is taking away money from things like troops and equipment for those troops. There are [also] new concerns about the future viability of Trident.
“The defence budget is an important thing, but there are much better ways of securing our country today.
“At the same time as adopting modern 21st century defence systems, [Britain] could also use this as an opportunity to have a break point with nuclear weapons internationally."
