How MI5 piled falsehood on falsehood in court in the case of a spy who abused women

MI5 lied to three courts in the case of a neo-Nazi spy who abused women.

MI5 tried to cover its tracks - scattering a trail of false and misleading evidence.

Security Service apologised for giving false evidence - vowing to investigate.

But High Court ruled that these inquiries were "deficient" and ordered a new investigation.

Two official reviews concluded that the senior officer who called me failed to recall telling me that X was an agent.

But material that MI5 and the government sought to keep secret shows that Officer 2 gave a detailed recollection of the conversation with me - until I exposed it as false.

All three claims were false, including about the conversations being off the record.

A formal record was created saying the plan was to call the BBC and "reveal the MI5 link to X" Notes of calls and meeting with Agent X show he approved the plan to reveal his MI5 role.

In a telling note, MI5 said X thought a meeting with me would "hopefully serve to counter some of the conclusions that the journalist had reached".
