I want to know the answer to the following question:
Who was the Prime Minister who reached this agreement with the US?
All the background I'm provided with is that "One of the terms of the agreement was that the airfield the US Army built would be used jointly by the US and the UK (which it was for the duration of the war, with RAF Transport Command relocating there from Darrell's Island in 1943).". Is that enough to answer the question?
Answer: no
