Most British posters are probably aware of the conspiracy theory that Harold Wilson was a KGB agent - the premise had been transformed into a very successful TL, Agent Lavender.
Allegations have also came up over the years that Michael Foot, another Labour leader, was also an informant for the Soviets, providing them with information up until 1968.
Ignoring the accuracy of these claims, let's imagine that, in an alternate timeline, the KGB is able to establish a web of control over the Labour Party. Soviet agents are able to establish themselves in senior positions within the party, including its leadership. Then, during the 70s, their cover is blown. MI5 are able to unmask the spies and reveal evidence beyond any reasonable doubt that the Labour frontbench is in the pay of the Soviet Government. Perhaps a few MPs flee to Moscow to confirm to any sceptics in the public that the incident is not an 'establishment coup'.
What would the implications of this be?
