3.8. No. 1 (Plain) Special Report} SUBJECT Reference to Papers (2) METROPOLITAN POLICE SPECIAL BRANCH ..day 1. The pattern of activity this week at Grunwicks seems to have settled down to a much less violent form than previously although still highly volatile. A significant reductionmintthe numbers attending the scene has taken place yesterday and today - about 600 and LL00 respectively. 2. Although this is in line with the recommendations made by APEX that pickets should be limited?to 500', it?l'fa's undoubtedly?been a disappointment to the Strike Committee in view of their belief that pressure must be maintained on the compamf. They have issued a public statement to the affect that there must be an escalation of the mobilisation of the trade?union movements support for this week's picket. 3. It has become apparent that many of the Trotskyists who have been attending the picket lines on a_daily basis have become disen?hanted for the following reasons. Whilst still strongly in support of the strikers and the accompanying violence, they are disappointed that it has not been found possible to 'finish pff' the company quickly; the lack of co-ordination between the various groups taking part; the demonstrable success of police tactics in containing the overall situation. In addition, many are finding the financial strain of attending on an daily basis too much to bear. It can be expected that for the remainder of this week groups of Trotskyists will attend every day but their overall numbers will be much reduced from last week. h. it is also becoming clear that the Communist Party is taking an increasing interest in events and is committed to mobilising maximum support from within the trade union movement for the strikers. Everyday the 'MOrning Star' gives prominence on its front page to the previous day's events, in the course of which it usually gives details oft commitments made by various trade unions to take part in the picketing. The Communist Party supports the 'day of action' called by the Yerkshire miners for 11 July and can be expected to use all its resources in mobilising trade union participation. Fof Brent Trades Council who appears to be in air effective control of the Strike Committee, is known to be a Communist sympathiser, and there is little doubt that he has probably been in daily contact with Communist Party headquarters in London to discuss tactics. Rage: No. 2, -n a. ..-..- 5. However, any attempt to assess the numbers of persons likely to attend the picket lines on the remaining days of this week must inevitably, in view of the large trade union involvement, be speculative. The 'Mbrning Star' announcements indicate that there will be an increase in the number of pickets on wednesday and Friday of this week but from past experience it would be fair to assume that this increase will only be moderate and will not approach the large turnout achieved during the latter part of last week. 6. The following details are known concerning the remaining days of this week: wednesday 29 June The London Region have called for a 'mass picket' by their members (building workers). On Friday 2h June UCATT were present at Grunwicks complete with ornamental banner; however, on that occasion no more than 7 or 8 supporters appeared to comprise this group. A elegation of dockers will be present from the Royal Group ~eDocks. It is known that several members of the main Trotskyist groupsbelieve that there will be a large turnout on wednesday. The specific reasons for this belief have not become apparent and there has been no call from their executive for a national turnout. A coachload of Socialist workers Party supporters is leaving ?at cm; hours on 29.6.77 to take part in the morning picket. Thursday_30 June A delegation of is expected. It is not thought that this delegation will be large in numbers for as far as is known at present, no arrangements have been made in .I for the use or hire of any extensive quantity of transport. However, the mere threat of any strong action by seems to have a strengthening effect on the other trade unionists, and it may be that several delegations or groups will turn up in the hope of seeing some 'action'. Friday 1 July NATSOPA have stated they will be present to demonstrate on this day. The national officers of the union are expected to head the delegation and invitations have been extended to London branches of other print unions. The contingents will travel from Fleet Street by coaches. No. 21 Page No. 3. 1 The Executive of the CPSA union are expected to lead a delegation on this day. Past experience suggests that a CPSA delegation is likely to be modest in numbers. 7. To summarize - it would appear that according to present information the mass picketing will continue for the remainder of this week, and it is unlikely that the numbers will fall much below 300, or exceed 700 maximum. It can be expected that the energies of active trade unionists will be directed with increasing vigour towards a 'climax' on 11 July. In the meantime, it is apparent that they do not intend to let interest wane and will therefore do their utmost to maintain the picketing at its present level. 8. In relation to the "mass turnout? on 11.7.77, every effort is being made by this Branch to ensure that a com rehensive appreciation of the situation on that day Detective Sergeant Submitted: Chief Inspector . .- . i I guj'lLr
