It should come as a surprise to precisely nobody that I will be voting for the amendment. I cannot in all conscience stick my hand in the air in support of buying weapons of mass destruction whose only purpose is to kill innocent civilians. I just can't do it.
It seems obvious to me that if we spent our billions on humanitarian aid in the world's flash points, then that would have a much greater impact on world peace than keeping a nuclear arsenal, no matter how small. Bottom line is I don't want a nuke with my name on it killing hundreds of thousands of people.
That is the exact point I asked Shirley Williams during her Q & A at Scottish Conference on Saturday.
Another worry I have is that if we go for abandoning continuous deterrence, what effect would it have on an international crisis if we started loading them onto a sub. It's bound to ramp things up and even provoke a pre-emptive attack of some description.
I am not hugely hopeful that that the amendment will pass, but I have to support it.
