Now Pride's Purge has suggested the decade may have been stranger still:
After the 1974 election, negotiations began between the incumbent Prime Minister Edward Heath's Conservative Party and Jeremy Thorpe's Liberals to form a coalition government together.
In 1974, Cyril Smith was one of the leading lights of the Liberals and he most certainly would have been offered a ministerial seat in any Conservative-Liberal coalition government cabinet.
Needless to say, the allegations of abuse the police were preparing against Smith would have scuppered any hopes of a coalition agreement.
And when did the Smith abuse file disappear after MI5 requested it from Special Branch? Yes, you've guessed it.
In 1974 - sometime around the same time Smith's Liberal Party were negotiating a coalition agreement with the Tories.
It looks suspiciously to me like elements of MI5 decided they were not going to allow negotiations to keep out a Labour government to be scuppered by such a trivial matter as a child abuse scandal involving a probable future cabinet minister.
What do you think?Well, what do you think?
I am not convinced, but it is a lovely theory. And the seventies were strange days indeed.
