====Partial Test Ban Treaty (1963)====
Macmillan's previous attempt to create an agreement at the May 1960 summit in Paris had collapsed due to the [[1960 U-2 incident]]. He was a force in the negotiations leading to the signing of the 1963 [[Partial Test Ban Treaty]] by the United Kingdom, the United States and the Soviet Union. He sent [[Quintin Hogg, Baron Hailsham of St Marylebone|Lord Hailsham]] to negotiate the Test Ban Treaty, a sign that he was grooming him as a potential successor.{{sfn|Thorpe|2010|pp=551–552}}

President Kennedy visited Macmillan's country home, [[Birch Grove]], on 29–30 June 1963, for talks about the planned [[Multilateral Force]]. They never met again, and this was to be Kennedy's last visit to the UK. He was [[Assassination of John F. Kennedy|assassinated]] in November, shortly after the end of Macmillan's premiership.{{sfn|Thorpe|2010|pp=504–05}}
