Ultra was the designation adopted by British military intelligence in June 1941 for wartime signals intelligence obtained by breaking high-level encrypted enemy radio and teleprinter communications at the Government Code and Cypher School (GC&CS) at Bletchley Park. Ultra eventually became the standard designation among the western Allies for all such intelligence. The name arose because the intelligence obtained was considered more important than that designated by the highest British security classification then used and so was regarded as being Ultra Secret. Several other cryptonyms had been used for such intelligence.

It was to be executed in 1942 and acted as a contingency alternative to Operation Roundup, the original Allied plan for the invasion of Europe in 1943.

Operation Claymore was a British/Norwegian commando raid on the Lofoten Islands of northern Norway during the Second World War. The Lofoten Islands were an important centre for the production of fish oil and glycerine, used in the German war economy. The landings were carried out on 4 March 1941, by 500 men of No. 3 Commando, No. 4 Commando, and a Royal Engineers section, and 52 men from Norwegian Independent Company 1. Supported by the 6th Destroyer Flotilla and two troop transports of the Royal Navy, the force landed almost unopposed. The original plan was to avoid contact with German forces and inflict the maximum of damage to German-controlled industry. They achieved their objective of destroying fish oil factories and some 3,600 t of oil and glycerine. The force returned with some 228 German prisoners, 314 Norwegian recruits, and a number of Quisling regime collaborators.

The whole affair also highlighted the weakness of the constitutional convention of individual ministerial accountability, leading to its codification as the Ministerial Code by the Blair Government.
