Quoted by A Short History of the RSPCA Animal Hostel at London Airport. Pt. 2: International Activities.
Description:

'At a later Medical Research Council-convened meeting it was suggested further that 'the R.S.P.C.A. has its crank fringe who would, if they could, entirely suppress the traffic in monkeys to the United Kingdom for medical research purposes.' The RSPCA's proposals were thought unjustifiably 'obstructive to the shipment of monkeys.''

 

From original:

'There is one small amendment in the present version. The reference to the attendance at the July meeting of the Royal Society for the Prevention of Cruelty to Animals has been deleted. The  original version of this paper is at (69) on the file. It was revealed at the meeting that although the R.S.P.C.A. had agreed with the recommendations on the shipment of monkeys, they did not wish to appear to be associated in any way with the shipment of monkeys from overseas for medical purposes. If they were seen to be associated, it would cost them some sympathy among some of their supporters, and they might lose some subscriptions. The R.S.P.C.A. has its crank fringe who would, if they could, entirely suppress the traffic in monkeys to the United Kingdom for medical research purposes. One of the cranks is Mr. Peter Freeman M.P.

...

Dr. Green, the Chairman, said that the R.S.P.C.A. who had provisionally agreed with the terms of the recommendations for the humane shipment of monkeys, but who had subsequently refused to have their name appear on the document, had approached the Ministry of Agriculture with a view to the issue of regulations by H.M.G. for the carriage of monkeys. An inter-departmental meeting had been held on the 27th January (a record of this meeting is at (113) on the file). The R.S.P.C.A.'s recommendations went further than those of the July conference, and were in the Chairman's opinion, obstructive to the shipment of monkeys. The Departmental view was, he said, that there was no need for legislation, and the Ministries' representatives at the meeting on 27th January were determined that their own Minister should not be saddled with the responsibility for introducing legislation.'
