EDITOR—Johnson was appointed by the Attorney General to be a “special advocate” in around 2007, Declassified understands. These are specially vetted barristers who act for the purpose of hearing secret evidence in a closed court.
Special advocates “must undergo and obtain Developed Vetting (the highest level of HM Government security clearance) prior to their appointment”, government guidance states. Developed Vetting is required for individuals having “frequent and uncontrolled access to TOP SECRET assets or require any access to TOP SECRET codeword material”.
In 2016, Johnson acted as a special advocate in the case of Abdel Hakim Belhaj, a Libyan national who accused the UK government and MI6 of participating in kidnapping him and his pregnant wife, Fatima Bouchar. The UK government later apologised for its actions that contributed to Belhaj and Bouchar’s rendition, detention and torture.
