'Bunbury' (i) was a British intelligence deception in which a power station at Bury St Edmunds in the eastern English county of Suffolk was 'sabotaged' to add veracity to the 'saboteur' credentials of 'Mutt' and 'Jeff', a pair of Norwegians who had surrendered to the British immediately after being delivered by a German seaplane in April 1941 and then volunteered to become double agents (1942).

The two other sabotages 'performed' by the duo were 'Guy Fawkes' in November 1941 and 'Brock' in 1942.
