"We have Mr. Wright's allegation that a surveillance operation was mounted against Lord Wilson of Rievaulx when he was Prime Minister in the mid-1970s...Many criticisms can be made of Lord Wilson's stewardship—I have made some in the past and I have no doubt that I may make some more in future—but the view that he, with his too persistent record of maintaining Britain's imperial commitments across the world, with his over-loyal lieutenancy to Lyndon Johnson, with his fervent royalism, and with his light ideological luggage, was a likely candidate to be a Russian or Communist agent is one that can be entertained only by someone with a mind diseased by partisanship or unhinged by living for too long in an Alice-Through-the-Looking-glass world in which falsehood becomes truth, fact becomes fiction and fantasy becomes reality. The result of the allegation has been substantially to fortify the view that I expressed in a letter to The Times 18 months ago, which is that MI5 should now be pulled totally out of its political surveillance role."
