British supermarket chain Tesco has unveiled executive changes to position the company for delivering continued market-leading performance.

Matthew Barnes has stepped down from his position as UK CEO to explore new ventures.

Ashwin Prasad, currently serving as Tesco Group’s chief commercial officer, is set to take over the role from 30 June 2025.

Prasad has been part of Tesco’s executive team since 2020, and has helped navigate the company through recent supply chain challenges, leading the trading strategy and digital marketing advancements for the business.

Natasha Adams, current CEO for Tesco Ireland and Northern Ireland (NI) , will assume a newly established position on the retailer’s executive committee as chief strategy and transformation officer from 9 June.

In a related move, Geoff Byrne, who holds the position of chief operating officer in Ireland, will be promoted to CEO for Tesco Ireland and NI.

Byrne has extensive experience, having been with Tesco since 1989.

As chief operating officer in Ireland since 2014, he has managed retail operations across all stores, distribution networks, property and the grocery/home shopping business.

All executive positions will continue reporting to group CEO Ken Murphy.

Ken Murphy stated: “We are winning in the intensely competitive markets we serve and making strong progress delivering our strategic ambitions. The changes to our executive team, which draw on strong internal talent, will set us up to continue delivering a market-leading performance.

“Our strategy focuses on being brilliant at the basics whilst stepping forward on big strategic initiatives – by becoming increasingly digital and delivering more personalised customer engagement, through new growth avenues such as Marketplace, and by further developing leading capabilities such as retail media. We are pleased to be making strong progress against our growth ambitions, and the newly created role of chief strategy and transformation officer will set us up even better to continue winning in the future. I am delighted to appoint Natasha, one of our most experienced and capable leaders, into this role.”

In January 2025, Tesco announced plans to cut 400 jobs in a strategic move to streamline its operations.
