“Former MI5 officers guard many secrets. But, as Dame Stella Rimington well knows, they can tell their own stories. A former agent has to seek prior approval for publication from his or her former employers and, if it is not given, any dispute will ultimately be adjudicated by a High Court Judge with all the usual safeguards to ensure a fair trial. Or so it was thought until the Court of Appeal gave judgment in A v B.”
