Two "Notes for the Record" from March 1, 1967, describe the vigorous discussions between senior UK government figures, including Harold Wilson, Foreign Secretary George Brown, Minister of State for Foreign and Commonwealth Affairs Lord Chalfont, and chief scientific adviser to the government Solly Zuckerman. Brown argued that "our posture on the matter should be distinctively European rather than one of supporting the United States against other European countries." Wilson was even more explicit, stating that "our approach should be that of a European power discussing the matter with European partners and not seeking to fight American battles." Wilson was keen to let Washington take the lead so that his government might avoid upsetting the French, as had happened with the debates over De Gaulle's 1966 withdrawal from the NATO command structure.

Before and after de Gaulle's November 1967 veto of Britain's second EEC application, Britain's position in Europe and its relationships with existing EEC states shaped the UK's role in the NPT negotiations. Prior to 1967, London canvassed opinion in EEC capitals, particularly in Bonn. As the NPT negotiations wound their way through the Eighteen Nation Committee on Disarmament (of which the United Kingdom was a member) in 1967, British representatives reported deep-seated concerns in Bonn, Brussels, the Hague, Luxembourg City, Paris, and Rome that a non-proliferation agreement might threaten the continued functioning of EURATOM, namely that its power might be subsumed into the IAEA, opening non-nuclear-weapon states (NNWS) up to commercial espionage conducted by inspectors representing the nuclear-weapon states (NWS).

This telegram detailed the conditions under which the West German's would ratify the NPT, which depended on the results of EURATOM-IAEA safeguards negotiations.

In this memorandum, Wells reported on comments that West German Minister for Scientific Research Hans Lenz made during a meeting at the Atomic Energy Convention. Noting that West Germany had been holding talks with the French and EURATOM about building a reprocessing plant at Karlsruhe, Lenz “implied that this proposal quite likely had resulted in reports that Germany might be undertaking a cooperative program with France in the development of their gaseous diffusion plant at Pierrelatte.” Lenz then reaffirmed West Germany's commitment to the 1955 Brussels Treaty pledge, declaring that West Germany would not initiate action to develop military applications of atomic energy.

As West Germany and The Netherlands developed ultra-centrifuges without a classification policy, the AEC discuss ways to keep the technology under wraps without arousing suspicion from the other members of Euratom.
