How much would a new base, that realistically could only be built on the Cumbrian coast, as the warheads can't be stored in a populated area, plus the submarines need a deep water port, so dredging would be needed, cost on top of renewal?
Do you think we'll ever get round to renewing Trident, currently based in Scotland, that's supposed to be discussed in Westminster this year and if so where's it going to be based? Will an independent little England still be on the UN security council with no nuclear deterrent?
