The controversy surrounding Peter Mandelson's failed UK security vetting ahead of his appointment as ambassador to the US has brought attention to the jargon used by the national security apparatus. The decision to deny clearance was later overturned, and the case is now being scrutinised by the Foreign Affairs Select Committee.
Key figures Morgan McSweeney, formerly Keir Starmer's chief of staff, and ex-Foreign Office chief Philip Barton are giving evidence about who knew what and when. The hearing has highlighted the abbreviations and archaic language used in parliamentary processes.
Understanding terms such as 'DV' (Developed Vetting) is crucial to following the story. DV is a high-level security clearance required for access to sensitive information. The Mandelson case has thrown these phrases into the spotlight amid political fallout.
