I am absolutely certain that the allegation that this is anything to do with the security services or GCHQ [...] is being put out by newspapers, who I think feel rather guilty that they are using plainly tapped telephone calls." The Labour Party, then in Opposition, accused Kenneth Clarke of irresponsibility, issuing a statement: "He has to show that he is taking these allegations seriously, otherwise he will be perceived as being unable to control an organisation for which he is responsible." Official position John Major's government eventually published two reports, both of which cleared MI5 and MI6 of involvement in the "Royalgates" tapes. One of these was the annual report of the Interceptions Commissioner, Lord Bingham of Cornhill, who oversaw the intelligence-gathering practices of the security services. Excerpt follows: "[Lord Bingham] was impressed by the scrupulous adherence to the statutory provisions [against misconduct] of those involved in the [intelligence-gathering] procedures." In a clear reference to the "Squidgygate" affair, he commented on "the stories which occasionally circulated in the press with regard to the interceptions by MI5, MI6 and GCHQ," stating that such stories were, in his experience, "without exception false, and gave an entirely misleading impression to the public both of the extent of official interception and of the targets against which interception is directed." Conservative MP Richard Shepherd called the official reports: "two old buffers saying that in their opinion the security services act with integrity." The National Heritage Secretary Peter Brook gave MPs "a categorical assurance that the heads of the agencies concerned have said there is no truth in the rumours." The Queen was so disturbed by the "Squidgygate" episode that she requested that MI5 conduct an investigation to discover the culprit or culprits. Since the motive could not have been financial, said the investigators—the only winners were the radio hams and the press—it must have been political. In 2002, Diana's former Personal Protection Officer, Inspector Ken Wharfe, stated that the investigation had "identified all those involved, but for legal reasons I cannot expand further, and nor is it necessary to do so." Wharfe added that: "It does [...] lend credence to the Princess's belief, so often dismissed by her detractors, that the Establishment was out to destroy her."
