GREAT BRITAIN: New Ambassador

Keystone of British foreign policy is, above all, to remain on intimate, friendly terms with the U. S. So in the top ranks of British diplomats is her Ambassador to the U. S. Since 1930, Britain's representative at Washington has been Sir Ronald Lindsay, a legate of long experience in Russia. Persia, France, Egypt, Turkey, Germany. His two marriages were with U. S. women: first to Martha Cameron, daughter of former Pennsylvania Senator J. Donald Cameron, who died in 1918, next to Elizabeth Sherman, daughter of the late Colgate Hoyt of New York.

For almost a year the 61-year-old Sir Ronald has wanted to retire. Early this week the British Government granted his wish, appointed as a successor an equally high-powered statesman, the 57-year-old Marquess of Lothian. He will take his Washington post soon after the visit of King George VI and Queen Elizabeth to the U. S. in June.

Lord Lothian's assignments to foreign countries have been rare; his early duties were confined largely to remote spots of the British Empire in Africa and Asia. He is better remembered in the U. S. as Philip Henry Kerr, secretary from 1916 to 1921 to David Lloyd George, Wartime British Prime Minister. He was raised to the peerage in 1930. A Liberal peer, in later years he has become more a Conservative, has warmly supported Prime Minister Neville Chamberlain's policy and is usually counted among the members of Lady Astor's "Cliveden Set."
