Liam Fox explains (to ‘Red Andy’, no less) the big picture issue raised by Spygate:

“I think that the Labour left during the Cold War were extremely unhelpful to this country. We believed that we should see off Communism, we believed we should see off tyranny… I certainly think the Labour left were the Soviet Union’s useful idiots during that period…

“Jeremy Corbyn and others were very useful to the Soviet Union during the Cold War because they undermined the arguments of the West… I think in the broadest sense he was undermining the security of our country by siding with the Soviet Union in that argument and I think that was very damaging to the country. Luckily it was our side of the argument not Jeremy Corbyn’s that won the day. I think he certainly undermined the security of the United Kingdom by their one-sided disarmament and their very clear preference for a Soviet style communism during that period – fortunately we beat them then and we have to beat them now.”
