Shortly after he became Foreign Secretary, Cook ended his relationship with Margaret, revealing that he was having an extra-marital affair with one of his staff, Gaynor Regan. He announced his intentions to leave his wife via a press statement made at Heathrow on 2 August 1997. Cook was forced into a decision over his private life after a telephone conversation with Alastair Campbell as he was about to go on holiday with his first wife. Campbell explained that the press was about to break the story of his affair with Regan. His estranged wife subsequently accused him of having had several extramarital affairs and alleged he had a habit of drinking heavily.
