Who is or is not Defence Secretary in the event of a Labour government is surely completely irrelevant. We will have a Prime Minister who has stated that while he is in favour of keeping the Trident boats, he would not authorise the use of nuclear weapons, thus making their whole raison d'etre completely pointless and at at one stroke removing the UK from the "top table". Some may argue that would be a good thing, and that we no longer need to be a nuclear power, but if that is going to be the case let's scrap the subs and save the country umpty ump billions, not keep them on to appease the unions in the defence industries, which seems to be Corbyn's plan.
