The spooks like to infiltrate political parties.
It is quite possible that many of the top people in the Scottish Socialist Party (SSP) work for the security services.
Tommy Sheridan is a Scottish socialist politician.
He is one of two co-convenors of the left-wing Scottish political party Solidarity.
He was the convenor of the Scottish Socialist Party, but in 2004 he was asked to resign from this post, by a unanimous vote of the Executive Committee.
The News of the World then alleged that Sheridan had visited a swingers clubs in Manchester and engaged in adulterous affairs with two women.
Sheridan, who claims to be a teetotaller, reportedly drank champagne and consumed cocaine during an extramarital liaison.
In 2006 Tommy Sheridan won an action for defamation against the News of the World.
On 10 October 2006, BBC News reported that Grampian Police were investigating a claim by Fiona McGuire, who had been a witness in the trial for the News of the World, that she had received a death threat through the post. 
On 26 August 2007, the Sunday Herald reported that John Lynn had been questioned by detectives about allegations of witness tampering.
Lynn is reportedly an associate of Paul Ferris, a former Glasgow gangster, who has become friendly with Sheridan.
The report said Helen Allison, who claimed in court that she saw Sheridan having sex in a Glasgow hotel, had been approached by Lynn who asked her not to give evidence. Lynn was once jailed for 17 years for shooting an Ulster barman.
In October 2006, the News of the World published what it claimed was a video recording of Tommy Sheridan admitting he visited a swingers club in Manchester on two occasions and that he (Sheridan) admitted this at an Executive meeting of the SSP.
The tape had been made using a hidden camera by SSP member George McNeillage in McNeillage's house after he invited Sheridan there. McNeillage had been one of three best men at Sheridan's wedding. 
Tommy Sheridan does not appear on the video at any time.
The newspaper has not been able to produce any images from the video showing Sheridan's face and Sheridan says the video is a fake.
Sheridan agrees his voice is on the tape but suggests it was "spliced" with clips of someone else's. 
The News of the World claimed four independent voice analysts confirmed that the voice on the tape is Tommy Sheridan's.
But in an interview with the BBC a forensic speech scientist, Peter French, said: "Experts should never say conclusively they have identified a person and this kind of evidence should never solely be used to bring a criminal trial".
Sheridan then suggested that MI5, the Bush government, the SSP and Rupert Murdoch conspired to concoct the videotape to undermine his campaign for an independent socialist Scotland.
In 2007, Tommy Sheridan was charged with perjury.
In October 2010, he appeared together with his wife at a trial for perjury related to the 2006 court case.
Sheridan claims he is the 'victim of an MI5 plot' - The Scotsman
Tommy Sheridan has suggested that MI5 and Rupert Murdoch had conspired to concoct the famous videotape.
In a political rally, Tommy Sheridan claimed that the video allegedly showing him admitting to visiting the swingers club was "utterly untrue".
"I said I was the victim of the mother of all stitch-ups," he said. "I don't think there is anyone in Scotland who can doubt that this has been an attempted stitch-up from day one.
"But it's a stitch-up that has unravelled. I say here today that the News of the World have tried to produce, in collusion with others, dodgy minutes, dodgy tapes and dodgy geezers to make allegations against me.
"They are completely and utterly untrue. We beat them in court and that is what they can't stand - because they were humiliated...
"Just as Freddie Starr did not eat his hamster, then the video has been concocted, manufactured and presented...
"I would not be surprised if the state is involved.
"The state has a fine history of trying to destabilise and undermine socialist movements or trade union struggles. When the history of this whole episode is written about, I think you'll find that MI5 was involved."
Sheridan claimed the video tape was as genuine as footage of Elvis Presley jamming with Noel Gallagher.
Sheridan claimed he had never been in the house where the video was filmed.
He said there was more than one voice on the tape, proving it had "clearly" been spliced "on several occasions".
Is Tommy Sheridan working for the spooks, or is he being undermined by the spooks?
