Cathy Massiter is a UK spook who in 1985 turned whistleblower after 2 years of spying on CND.


Massiter as an MI5 officer had been responsible for the surveillance of CND from 1981 to 1983. In 1985 she resigned and made disclosures to a Channel 4 20/20 Vision programme, "MI5's Official Secrets".[1][2] She said that her work was determined more by the political importance of CND than by any security threat posed by subversive elements within it, and argued that the organisation was contravening the rules governing its practices.[3]

Richard Norton-Taylor wrote in 2001 that Massiter's revelations in 1985 had never been officially challenged by the government.[4]
