Marcia Williams, later known as lady Falkender, was a key adviser to the British Prime Minister Harold Wilson. She began working for him as a secretary and over time became his main associate.
During her career when she was both a positive and a negative influence on the Prime Minister. She helped Wilson to become the Labour Party leader and the Prime Minister, she was a loyal counsel and manager of his office.
Her personality led to the fact, that over time she became a liability. Especially during second Wilson's term in office, when she became a centre of several scandals, which damaged her reputation and Prime Minister's legacy.
Lady Falkender therefore remains a controversial individual of the British political history.
