Their historic agreement at the Elizabethan mansion in Hurstpierpoint took place on October 13, 1918 and led to a series of top level talks that brought to an end the First-World-War.

A plaque commemorating the event can be found in the Great Hall where Lloyd George met with some of his cabinet members and close political allies, including former prime minister Arthur Balfour and two future prime ministers - Winston Churchill and Bonar Law.

Lord Riddell, the owner of the News of the World, had rented Danny off the Campion family as a country retreat for Lloyd George between July and October 1918.

According to Lloyd George's biographer John Campbell: "There was a public and private reason for getting Lloyd George into the countryside. It was a bolt hole from the pressures of London and a place where he could carry on his private affair with his secretary and mistress Frances Stevenson."
