David Quarrie asks if there is any opposition to Labour madness of spending billions on replacing Trident (Folly of where our cash goes, Letters, January 6).

Certainly there is. Green Party Euro-MP Caroline Lucas has been a leading voice in the calls to not replace Trident. Replacing it would do nothing to stop the global spread of nuclear weapons to states like Iran and North Korea.

It is chasing phantoms of the Cold War, and does not tackle the much bigger security threats of international terrorism and climate change. Tackling these would be a far better way to spend our security budget.

Caroline Lucas is visiting York on Thursday, February 8, and will be giving a talk about Trident replacement in Alcuin teaching block at the University of York at 3.15pm. All are welcome to come and debate this crucial issue.
