The journalist and peer died following a short illness, according to his son, MP Jacob Rees-Mogg. Jacob told the newspaper: "It has been a mercifully short illness. He was very prepared for it." Lord Rees-Mogg joined the Financial Times after leaving Oxford University and later moved to a three-year deputy editorship at the Sunday Times. He became editor of The Times in 1967, replacing Sir William Haley, and headed the daily broadsheet through a difficult 14 years in its history.
