Lancelot Oliphant

Sir Lancelot Oliphant, KCMG, CB (8 October 18812 October 1965) was a British diplomat, Ambassador Extraordinary and Plenipotentiary to Belgium, Minister-Plenipotentiary to Luxembourg and Director General of the Foreign Office.

His decision that Britain would neither join nor fund a joint partnership with Saudi Arabia to explore for oil, thus forcing the Saudis to cooperate with the United States, left him with the unwanted sobriquet ''The diplomat who said 'No' to Saudi oil''. Provided by Wikipedia
