TRIPLEX

The code name assigned to XXX material—information acquired from the illicit copying of the content of diplomatic bags sent to and from diplomatic missions in London during World War II. Conducted by a joint MI5–Secret Intelligence Service unit dedicated to gaining surreptitious access to the attaché cases carried by
diplomatic couriers, TRIPLEX constituted a major breach of the Vienna Convention and therefore was considered an extremely sensitive source.
