Chief digital director Clodagh Moriarty adds responsibility for stores to her expanded remit as retail and digital director, while chief marketing officer Mark Given has been granted a seat on the retailer’s operating board.

Moriarty’s promotion is an important indicator both of the high regard in which she is held internally and the future direction of Sainsbury’s under Roberts.

Moriarty joined Sainsbury’s a decade ago from consultancy Bain & Company having originally trained as an electrical engineer.

In her previous role, she was responsible for creating and leading the retailer’s digital strategy across Sainsbury’s, Argos, its Nectar loyalty scheme and Sainsbury’s Bank.
