| Ian Cameron|
According to David Leigh:
- So at Stormont Castle the MI6 officer was relived by Dennis Payne of MI5, and the intelligence controller at Lisburn, Craig Smellie of MI6, was replaced by Ian Cameron of MI5. Unfortunately, though these moves made sense and initially all went smoothly, much later MI5 also committed in blunders in Ulster.
Fred Holroyd, an Army officer who had worked for MI6, recounts that he was called into Cameron's office a few days after Smellie's departure:
Holroyd also describes having a second conversation, immediately afterwards, with an SAS officer, Major Keith Farnes:
- He asked me what I though of Cameron. I said, quite honestly, that I hadn't been very taken with him. Farnes told me that I was not the only one to feel like this: an NCO in the Intelligence Corps who had been running ten different sources in the IRA had seen them all murdered within a few days of MI5 taking over operations. He had gone into a bunker and shot himself in the head. In Farnes's words, 'MI5 leaks like a sieve!'
Raymond Murray comments on this story: "I find no record of ten informants having been shot by the IRA at this time."
