Tesco‘s Head of Transformation Jill Easterbrook will leave Britain‘s biggest supermarket next month. 

After more than 15 years at the grocer, Easterbrook will be moving on, a decision that has greatly surprised the company who were seemingly ignorant of her intentions and are unaware if she has a new position lined up. 

“After 15 years at Tesco, Jill Easterbrook has decided to leave the company early next year,” a Tesco spokesperson said. 

“Jill has held a number of leadership positions across Tesco including running UK Clothing, leading our Developing Businesses and most recently, overseeing the first phase of our turnaround as Group Transformation Director. 

“We‘d like to thank Jill for her outstanding work during her time at Tesco and wish her every success for the future.” 

Easterbrook was almost the right hand man to CEO Dave Lewis, and an integral part of his plans to turn Tesco around following the accounting scandal of 2014. She is the second senior official to step down since Lewis took up his position, following Chief Information Officer Steve McNamara earlier this year. 

During her 15 year tenute, Easterbrook held a number of positions, including Director of Clothing & ROI and Chief Customer Officer, before taking on the role of Head of Transformation in February this year.
