From an article published in a 1985 edition of the Monday Club magazine 'Right Ahead' which was heavily critical of the BBC and of what Tebbit regarded as the corporation's left-wing bias. Tebbit was referring to an episode of the popular BBC science-fiction series Doctor Who entitled 'Pyramids of Mars' which he had recently seen - he perceived a "wasteland version of 1980" featured in the episode to be a symbolic, allegorical and propagandistic attack on the Thatcher government. Tebbit was apparently completely unaware that the episode in question was actually filmed in 1975, four years before Thatcher had even come to power.
