For legal reasons he can only be named as ‘Journalist F’, but today this young member of The Daily Mail’s editorial staff is in hiding as threats and invective continue to spew from Paul Dacre’s office after their top secret editorial formula was leaked to the press. Journalist F, rumoured to be less than five years in the job, somehow gained access to Dacre’s high-security office, known in journalistic circles as ‘Fortress Britain’, and saw the secret formula tacked to the wall. Shocked by its similarity to a public transport system so often maligned within The Daily Mail’s own pages, he rolled it up, put it under his jacket and walked out of his job into a media firestorm.
