MI5 K Branch
K Branch was a former division of MI5 responsible for counter-espionage in the service's organisation from 1968. Prior to this time, this had been D Branch. [1] The re-organisation was carried out by Michael Hanley as head of counter-espionage. Peter Wright claims that he persuaded Hanley and Martin Furnival Jones to include a formal mechanism for investigating penetration of the service.[2] K branch was reincorporated into a new D Branch in the service's organisation of 1994.[3]
