As an SDS officer
According to the Undercover Policing Inquiry it is not known what branch of the Socialist Workers Party he was deployed into. His cover surname has not been discovered. During deployment told another undercover that he had fallen in love with a member of his target group and had divorced from second wife in 1979. A gisted note from the Inquiry provides the following:
- During his deployment, another SDS UCO recalls being told by HN300 that he had fallen in love with one of his target group and wanted to disclose to her that he was an undercover officer. HN300 was withdrawn from the field. HN300’s family from his second marriage confirmed that he met his third wife whilst deployed on the SDS and that she sometimes referred to him as ‘Jimmy’. They had a child. This third marriage also ended in divorce. The woman then moved overseas in the 1980s and it has not been possible to contact her. It is understood that she has remarried.
