Wallis had already filed for divorce from her second husband on the grounds that he had committed adultery with her childhood friend Mary Kirk and the decree nisi was granted on 27 October 1936. In November, the King consulted with the British prime minister, Stanley Baldwin, on a way to marry Wallis and keep the throne. The King suggested a morganatic marriage, where he would remain king but Wallis would not be queen, but this was rejected by Baldwin and the prime ministers of Australia, Canada, and the Union of South Africa. If the King were to marry Wallis against Baldwin's advice, the Government would be required to resign, causing a constitutional crisis.
