We have just put online a number of documents
that offer us a glimpse into a rarely seen aspect of Margaret Thatcher’s prime ministership. These documents come from folder number 494 in the PREM19
series of Margaret Thatcher’s Prime Ministerial papers.
Entitled ‘National Union of Mineworkers: National Miners Left Club’, the
folder gives us an insight, albeit sketchy, into the secretive work of a little-known
Cabinet Office unit.
Two items from PREM19/494 are of
particular interest. The first (see here)
contains two documents. One appears to be a coversheet that would originally have
been attached to another document, in this case a report
numbered IAG(80)10. The coversheet states that owing to the ‘very sensitive
nature’ of the document in question, ‘it must not be placed on a normal
Departmental file’, but must instead be returned to the Cabinet Office once it
has been read. It is presumably because these instructions were followed that
the report is not present within PREM19/494. Nevertheless, an annotation on
the coversheet (dated 12th March 1980) gives us an idea of the
report’s content. The note, signed by Clive Whitmore (MT’s Principal Private
Secretary), is transcribed below:
Prime MinisterUnder this note MT writes, 'Yes please'.
A revealing indication of Mr Vic Allen’s influence in NUM matters.
I think that we should ask whether there would be advantage in exposing the existence and activities of the Miners’ Left Club. Shall I seek Sir Robert Armstrong’s advice?
How was this information obtained
in the first place? Armstrong’s minute
to Whitmore talks about the risk of ‘endangering sources’ by publicising the information, so it is natural to infer that a source or sources within the NUM were passing information out, and that this information was finding its way into government reports. Beyond this, however, we
can only speculate, and speculating about such a controversial area of history
is perhaps unwise. However, what we can do is return to the documents we have,
and see what other hints we can glean from them.
Let’s go back to our first item, the file containing
the annotated coversheet for the missing report. Also contained in this file is a note from
Whitmore to Armstrong dated 17th March 1980, in which Whitmore does
as he says he would, and seeks advice on ‘whether there would be advantage in
exposing the existence and activities of the Miners’ Left Club’. Whitmore writes to Armstrong as follows:
The Prime Minister has seen the report in IAG(80)10 on the activities of the National Miners’ Left Club and she has asked whether this is not the kind of case where some publicity, arranged under Mr Deverell’s auspices, might be useful.
I should be glad to know what you think.
Who is this mysterious Mr
Deverell? The aforementioned minute from Armstrong to Whitmore doesn’t help us
much here, telling us only that Mr Deverell ‘has been examining the activities
of the National Miners Left Club in the hope of finding a way of [publicising
them] without endangering sources’. Nor can we find the answer by searching our own archive: the name 'Deverell' appears only in the two documents that we are currently looking at.
Fortunately, assistance can be found in the form
of Christopher Andrew’s 2010 history of the Security Service, The Defence of the Realm: The Authorized History of MI5. In Chapter 7, Andrew refers to MT's having held a meeting on the 21st October 1979 to establish a Cabinet Office unit that would 'use information
from
both open and secret sources to try to forestall industrial disruption’
(p.671). No record of this meeting exists in our archive, presumably
because
any such record (if it ever existed) was highly confidential and
therefore did not find its way into the PREM19 series. Nevertheless, we
can see from MT’s engagement diary
that the meeting was held at Chequers at 3pm, and was attended by the Foreign Secretary Lord
Carrington, Home Secretary Willie Whitelaw, Secretary of State for Industry
Keith Joseph, outgoing Cabinet Secretary John Hunt, incoming Cabinet Secretary
Robert Armstrong, and Clive Whitmore.
Andrew goes on:
John Deverell, then considered one of the Service’s [i.e. MI5’s] younger high-fliers, was seconded to run the unit, which Service records suggest became a one-man band. Sir Robert Armstrong agreed with Deverell that they would ‘firmly eschew any thoughts of black propaganda’ as the risk would far outweigh the likely gains. Deverell was tasked instead with submitting proposals for countering specific cases of industrial subversion for approval by the Home Secretary and, if appropriate, the Prime Minister. [pp.671-2]
Andrew then gives an account of
the unit’s ‘first successful ‘ploy’ in response to a strike-call by the
Amalgamated Union of Engineering Workers (AUEW) at the government-owned British
Leyland (BL) Longbridge plant’ (p.672). The strike-call was made in response to the firing by BL of Derek "Red Robbo" Robinson, a union shop steward and Communist Party member. The aim of Deverell's Cabinet Office unit was to undermine support for Robinson, and thereby to weaken support for strike action among trade union members, leaders, and the wider public.
The ‘ploy’ was to publicise the minutes
of a meeting of the Communist Party’s Midland District
Committee, minutes which, according to then BL chief executive Michael Edwardes,
made it ‘absolutely clear that the intention [of the joint committee of the
Communist Party and BL shop stewards] was to break the company’ (quoted in the
2002 BBC documentary series, ‘True Spies’ – transcript here). This information was bound to concern those members of the trade union who wished to pursue a less radical line in negotiations with British Leyland.
The minutes of the meeting (again, according to the True Spies documentary)
were obtained by an MI5 agent working within the Communist Party and the AUEW (Andrew's book confirms that the Security Service ‘obtained a copy’ of these
minutes, but does not explicitly refer to the existence of an MI5 agent within either the
Communist Party or the AUEW), and from there came into the possession
of John Deverell's unit in the Cabinet Office. Andrew explains what
happened next:
This secret information, leaked by Deverell, helped to lead to a collapse in support for strike action both among the union leadership and the union members, thanks in part to press reporting of the affair.…at a meeting with Thatcher and Whitelaw, Deverell obtained their approval for [the record of the meeting] to be passed to the BL chairman, Sir Michael Edwardes. To disguise the source of the minutes, they were placed inside a brown envelope with a Birmingham postmark. Edwardes showed them to the president of the AUEW, Terry Duffy, who was sufficiently impressed to postpone strike action. Edwardes also contacted the Sunday Times, whose journalists tracked down some of those mentioned in the minutes. [p.672]
With all this in mind we can now return to our newly uploaded documents with a much better sense of what they
show us. The final defeat of the call to strike action in support of Derek Robinson had occurred in
February 1980 (see here).
Our documents, concerning the NUM, are dated March 1980. It would therefore
appear that our documents indicate a desire on the part of MT for Deverell
to initiate another ‘ploy’ (possibly using similar tactics), this time directed
against the NUM. This new idea for a ploy comes hot on the heels of the one
that was successful at BL, and, like the BL ploy, apparently depends upon
secret information passed to the government from a ‘source’ (or sources) whose position
would have been ‘endangered’ by clumsy handling of the information.
In the case of the proposed NUM
ploy, however, there was little prospect of success. In his reply to Whitmore,
Armstrong notes that ‘the material which [Deverell] has immediately available
and for which there is overt collateral would not be likely to cause Communist
Party activists within the National Miners Left Club much embarrassment’.
Instead, Armstrong suggests that 'with the coalmining scene relatively quiet at
the moment, it would make sense to keep our powder dry, and our sources of
information open, until a time when they could prove particularly useful’.
As we all know, the 'coalmining scene' didn't stay 'relatively quiet' for long. So did the government ever make use of these ‘sources of information’? It’s impossible to say from the documents that we currently have, and perhaps we will never know. Nevertheless, we will keep our eyes peeled for further evidence as more documents are released by The National Archives over the coming years.
