The political conspiracy theory advanced by this film - plausible?
I really enjoyed (if that's the right word) this engrossing film. I understand from other comments on this forum that the film was partially based on real events, such as the Stalker Inquiry. But I'm wondering about the wider political conspiracy theory advanced in the latter part of the film: is that at all credible or merely part of the invented plot?
I quote from Roger Ebert's review:
One of the most astonishing things about this film is the way it uses real names, dates and places - charging a secret right-wing group with attempting to bring down not only the Labor government of Harold Wilson, but the Conservative government of Edward Heath, which followed, and which the group found too soft for their taste. The implication is that Margaret Thatcher became prime minister at least partly through this group's efforts.
