MI5 agent ‘abused and threatened’ ex-partner, BBC investigation reveals

Story made public after an attempt by the attorney general to gain an injunction to prevent broadcast

An agent working for MI5 with a background in rightwing extremism abused his former partner and used his connection with the domestic intelligence agency to threaten her further, according to an investigation by the BBC.

The man - known only as X for legal reasons - is said to have terrorised the woman and at one point attacked her with a machete and threatened to kill her, as shown in a video captured on her mobile phone. There was so much psychological terror from him to me, that ultimately culminated in me having a breakdown," the woman said.
