I suppose it's natural to dismiss references to the political beliefs of the people who made up the Labour Government at the time the TSR2 was scrapped.
Unfortunately for those who scoff at the talk of political sabotage, the break up of the USSR opened up access to information which indicates that there were Soviet agents and sympathisers in the Labour Party at that time.
What other country in the West would have had a former card-carrying Communist in charge of its Defences? The same Denis Healey who claimed he left the Party in 1939 became Secretary of State for Defence in 1964 and stayed in that job for six long years until Labour lost the 1972 election.
He was the longest serving Defence Minister ever and would normally have been promoted into a higher ministerial position.
Of course the Prime Minister at that time was Harold Wilson who has been directly accused of being a Soviet agent by defecting KGB officers.
It was Harold Wilson who, it is claimed, ordered the destruction of jigs, tools, blueprints etc so that any incoming Tory government could never restart the TSR2 programme.
So, how successful was Denis Healey during those six years?
Dunno, but I'll bet the Russians thought he did a great job!
