MI5 F Branch
Contents
History
In its earliest incarnation, F Branch was responsible for preventive intelligence in the MI5 organisation of 1916.[1]
A new F Division covering counter-subversion was established by Director General Sir David Petrie in 1941.[2]
Counter-subversion branch
In Dick White's 1953 re-organisation, F Branch had responsibility for counter-subversion at home, while E Branch was responsible for counter-subversion in the British Empire and Commonwealth.[3]
In 1972, F Branch director John Jones defined subversion as "activities threatening the safety or well-being of the State and intended to undermine of overthrow Parliamentary democracy by political, industrial or violent means."[4]
In 1976, Director General Michael Hanley established a separate FX branch to deal with Irish terrorism. Its director continued to report to the director of F Branch.[5]
Targets
The Left
Communist Party of Great Britain
In April 1976, a threat assessment by F2 section argued that the Communist Party of Great Britain (CPGB) was a major subversive threat in the trade union movement.[6]
Trade Unions
TGWU
In October 1970, MI5 obtained a Home Office warrant against the general Secretary of the TGWU, Jack Jones, because of his contacts with the Russians. MI5 head Martin Furnival Jones noted that Jones was unlikely to be charged with espionage, but the operation "could be of great value in particular to the Department of Employment and to the Government generally in the field of industrial disputes.[7]
National Union of Mineworkers
According to Christopher Andrew, MI5 was unable to provide the Government with a full intelligence picture during the 1972 miner's strike, because its remit only extended to figures such as the Communist Scottish NUM leader Mick McGahey.[8]
On 14 November 1972, MI5 obtained a Home Office warrant against Arthur Scargill, "to help establish the extent of communist influence on present negotiations in the mining industry."[9]
