>Viktor Suvorov is a great author.
He was a defector and MI5 asset for 40 years so take everything you read by him with a massive grain of salt. More of a salt boulder really, if you consider that a lot of his work was written by MI5 ghostwriters, or edited by them.
Yes it was MI5 not MI6. MI6 helped him defect, but MI5 was the one that made use of him.
