Who controls the media?
The story has existed for years but ask yourself why nothing has ever been reported, not that D notices were slapped on, but why no Fleet St paper ran the story(s).
The truth will get out, the genie is out of the bottle and I would suggest that the reputation of a former Home Secretary and a PM from the 70s is going to be well and truly trashed.
I would imagine "Kitty" though is feeling relaxed in their Caribbean retreat that has no extradition agreement with the UK.
