Princes at war: the British Royal Family's private battle in the Second World War

King George V predicted that his son, Edward VIII, would destroy himself within a year of succeeding to the throne.

In December 1936 he was proved right, and the world's press revealed the king was abandoning his throne to marry Wallis Simpson.

A life spent in the shadow of his charismatic elder brother left the new king, George VI, magnificently unprepared for the demands of ruling the kingdom and empire.

Drawing on personal accounts from the royal archives, Deborah Cadbury uncovers the very private conflict between George VI and his older brother.
