General Sir Richard Dannatt, the former head of the Army, has stepped down from his role as an advisor to David Cameron after a stay of only nine months. He was appointed to the post during last year's Conservative Party conference - just weeks after retiring as chief of the general staff.
An attempt to install him in the Lords was blocked in April on the grounds that he should wait at least a year before taking up a political role.
He clashed with Liam Fox, who has since been appointed Defence Secretary, for saying publicly he was brought in because the Tory front bench lacked 'expert understanding'. He was quite right and it still does.
Sir Richard said he always intended to step down after the election. On Saturday, in an interview on Sky News, he appeared to criticise George Osborne for insisting that the Ministry of Defence budget bears the full cost of replacing Trident.
“It is effectively being put on the table for discussion by asking the Ministry of Defence to pay for it, so the issue really is: how much safer will we be with a replacement nuclear deterrent as opposed to how much safer will we be with fast jets, aircraft carriers, lots of soldiers, tanks and artillery?”
If he's done nothing else in his short tenure, it is to be hoped his comments will widen the debate about Trident. Why are we storing a weapon we can't use without the authority of another country? Scotland doesn't want it and we have to make our voices heard.
