MI6 chief Sir John Sawers told 'you're not in Spooks' and to stop 'bragging' over Iran nuclear claims He told a group of around 100 officials at Civil Service Live, a conference in Olympia, west London: "I take great pride in the fact that, in the last ten years, over a number of jobs, I've been involved in an issue of global concern, and I feel that I as an individual [have made] an impact in the outcome of events." Lady Falkner, who is the Liberal Democrats" spokesman for Ministry of Justice in the Lords, told peers: "Sir John's comments could almost be construed as bragging. In my view, it would be best for the veneer of silence to descend on the Secret Intelligence Service once again. There is such a thing as "too much information," and today we have seen an illustration of that." Sir John had claimed that without MI6"s covert work, "you'd have Iran as a nuclear weapons state in 2008 rather than still being two years away in 2012." It is extremely rare for the head of MI6 to disclose details of operations by the intelligence service. The comments were only the second time that Sir John has spoken in public since he was appointed in 2010. Lady Falkner said the fact that Sir John made the comments in a seminar "Unclassified chat" at the conference "demonstrates a clear lack of judgment on the part of a senior official." Lady Falkner said: "It would behove our senior civil servants to express a clearer concern about the UK engaging in unlawful activities rather than indulging in "unclassified chats" which give a contrary impression. "This is not the TV programme "Spooks." This matter engages UK interests and security directly. There are serious issues about accountability to Parliament as well. The news came as ministers said a report produced by an aborted inquiry into allegations of British complicity in torture has been delivered to the Government and as much of it as possible will be published. Sir Peter Gibson's inquiry was scrapped by Justice Secretary Ken Clarke in January after fresh criminal investigations were launched into allegations that MI5 and MI6 were involved in the secret rendition of two Libyans back to Muammar Gaddafi's regime in 2004. In a written statement to Parliament, Mr Clarke said Sir Peter had produced a report on the inquiry's preparatory work "highlighting particular themes or issues which might be the subject of further examination." Mr Clarke said: "The Government is now looking carefully at its contents and remains committed to publishing as much of this interim report as possible." Sir John described the British cases as "chilling" and admitted that some of the activity of British agents when questioning alleged terrorists was "close to the line." Sir John also described his agents as "secret squirrels" and said that there was "always a danger" that agents could go too far when questioning suspects. Last week Sir John told the civil servants that American spies had "got so obsessed with getting a right answer" during the war on terror that they resorted to torture.
