Haydon, who was assistant merchandise director at Bhs before joining Tesco last year, oversees merchandising across the supermarket’s entire clothing business. She declined to comment on her new role, but confirmed she was leaving the supermarket group.
Tesco head of clothing Terry Green said: “I’m sorry that Cathy is leaving for personal reasons, but we wish her all the best.”
Haydon’s departure follows the resignation of Tesco design boss Lee Rees-Oliviere, who left to launch his own collection (Drapers, November 17).
M&S declined to comment.
