Edward VIII and King George VI
The Royal family were resentful toward Edward VIII following his abdication in 1936.
A letter from Edward to aristocrat friend Lord Beaverbrook - the former owner of the Daily Express and Sunday Express newspapers - shows Edward was warned by close relations to stay away from England so his brother Albert could establish himself as the new monarch after he stepped down to marry Wallis Simpson.
This was done to prevent tension between his mother Queen Mary, sister-in-law Queen Elizabeth and himself.
In 1939 - three years after he abdicated - he wrote: "Of course you know as well as I do, that it is for no other reason than for fear lest the attitude my mother and sister in law seem likely to adopt towards my wife may provoke controversy in England and adverse criticism in America, that I have been advised to postpone our projected visit to England this Spring, until after the King's and Queen's official journey to Canada and the United States."
Albert's - who became known as King George VI - rise to the throne has been documented in 2010's 'The King's Speech' which saw him struggle with public speaking due to a stammer.
