Overview

The SDS was initially set up to monitor the groups involved in organising the 27 October 1968 anti-Vietnam war demonstration in London. Its stated aim was to prevent a repeat of the disorder that broke out on an earlier anti-war protest in March 1968. 

The decision to continue the SDS after 27 October 1968 was made by senior Metropolitan Police officers and the Home Office just two weeks later after the demonstration. At first, two six-month extensions retained the unit until the end of 1969. Thereafter, between 1970 and 1989, extensions were granted annually by the Home Office. After 1989, the unit was allowed to continue without seeking formal permission.

Proposal to Continue

The Special Demonstration Squad, then called the Special Operations Squad, was set up in July 1968 to ensure that the clashes of March 1968 were not repeated at the next anti-Vietnam war demonstration, planned for 27 October 1968.

The October demonstration passed without too much trouble, as far as the police, politicians, and the media were concerned. Thus, the mission of the Special Demonstration Squad had been completed and its reason for existing had disappeared.

However, shortly after that march, Detective Chief Inspector HN325 Conrad Dixon  made a proposal to continue the squad. Senior Metropolitan Police managers exchanged a series of memos discussing this idea, beginning on 8 November 1968, less than two weeks after the 27th October demonstration.

The first memo was sent from Chief Superintendent HN2857 Arthur Cunningham , who headed C Squad, to the head of Special Branch, Commander HN151 Ferguson Smith.  On 11 November, Smith accepted Cunningham’s assessment that the SDS had been a success and should therefore continue. The only quibble was where to find the £3,000 to fund the unit.

Smith mentioned in this memo that MI5 was pleased to hear the proposal to continue the SDS, and had offered to contribute to the funding. On 13 November, Metropolitan Police Commissioner HN1877 John Waldron  accepted the proposal and agreed to request the required financing. 

The first extension was only for six months, until May 1969. At this point, a second extension, until December 1969, was agreed.

The plan that Conrad Dixon proposed in a paper on 26 November 1968 may have responded to earlier discussions between Arthur Cunningham and Ferguson Smith.

However, it is clear that although Cunningham and Smith saw Dixon’s plan on 26 November, they had by then already agreed to continue the unit. Therefore, the funding for the unit did not depend on Conrad’s version of the plan going ahead. 

Certainly, the way the unit operated soon deviated from Dixon’s original proposal.  For instance, one of Dixon's original 1968 squad members HN68 Sean Lynch’s deployment exceeded the maximum 12 months that Dixon had proposed in the paper by four years.  Lynch also took up positions of responsibility within some of the groups he infiltrated,again contrary to Dixon’s proposals.

Home Office civil servant James Waddell agreed to the extension to summer 1969, with reservations:

I also felt, however, that in an enterprise of this kind there was some slight danger of innovations like the one we are considering becoming an accepted part of the scene, so that discontinuance might be thought to be a drastic change hence the suggestion that we want to look at the matter again in mid-summer.

1969-1989

A letter from Special Branch dated 27 May 1969 acknowledged that, unlike in the run-up to the 27 October 1968 demonstration, there was no imminent threat of disorder. In fact, Assistant Commissioner HN1876 Peter Brodie  admitted that there had been a downturn in disorder and that the ‘protest Movement [no longer had a] unifying cause’. It requested the extension on the grounds that this might change.

Financial support and authorisation for the SDS to continue for a further six months was granted on 6 June 1969 by civil servant David Stotesbury, an assistant under-secretary of state, whowas signing the memo on behalf of his boss Waddell, who was on leave.  

Stotesbury’s only concern was the ‘unusual’ accommodation arrangements for the undercover officers – and that should the squad’s existence become public knowledge, it would embarrass the home secretary.

Towards the end of the second six-month extension, Special Branch managers decided to ask to renew the squad’s authorisation for a further 12 months, from December 1969 to December 1970.[[mps-0730219/13]] Justification for the request was that Special Branch did not consider it was ‘out of the woods yet’ and so needed to retain its undercover officers as a preventative measure.[[MPS-0728973/]]

An extension was again granted in a letter dated 21 December 1970 from James Waddell, who had consulted the new Conservative Party Home Secretary Reginald Maudling.[[MPS-0724130]] [[Footnote: This is the first explicit mention of a consultation with a home secretary]]

This is significant as it reveals that from 1970 onwards  both main political parties that governed Britain were aware of its existence.

And so the unit’s existence and Home Office support became normalised, exactly as Waddell had anticipated. From 1972 to 1983, the annual letter from Special Branch to the Home Office was apparently enough to continue authorising and funding the squad. [[MPS-0730903]] 

The Inquiry’s interim report noted that a Home Office file that contained information about interaction with the SDS was missing. It is not clear whether that file contained evidence that the squads operational details were communicated to the Home Office beyond the scant detail provided in the funding letters. 

However, the interim report assumes that Waddell, the Home Office civil servant who received the letters requesting the continuation between 1969 and 1975, [[]] must have been aware of the squad’s operations, at least in general terms. [[Interim]]

In 1984, the Home Office requested more details about the squad’s operations, but approval for the squad continued. In 1989, the Home Office said the unit could continue without annual approval. 

Instead, it asked only for notification, for the purposes of consultation, in case there was ‘any significant change to the squad’s role, targeting and operational practice’. [[1989 Annual Report, doc not uploaded.]]
