Palace letters
The Palace letters, sometimes labelled as the Palace papers, were letters between Queen Elizabeth II, through her Private Secretary Martin Charteris, and Australian Governor-General Sir John Kerr around the time of the 1975 constitutional crisis, in which Kerr dismissed Australian Prime Minister Gough Whitlam. The phrase 'Palace letters' originated in the work of Australian historian and Whitlam biographer Professor Jenny Hocking, who successfully overturned the Queen's embargo over these letters, as a reference to Buckingham Palace, the official residence of Elizabeth in London.
