Imagine that Jeremy Corbyn had flown in an intelligence operative from among his many contacts in the Middle East. And imagine that that intelligence operative had certainly not been a British citizen, and had probably not been a member of the Labour Party.
But then imagine that Corbyn had given that foreign intelligence operative a position in his publicly funded office from which to vet all potential Labour candidates for anything.
Yet Keir Starmer has just done this. A vote for any Labour candidate, in principle for any office whatever, and certainly for Parliament or for anything else with a reasonably high profile, is now a vote for a person who must have passed that vetting.
