A handoff built on patience, not panic
Tesco announced on October 7 that Chris Blatchford, currently group chief technology officer at Kingfisher, will become its next CTO and join the executive committee. What makes the move notable is not the hire itself but the calendar around it. Blatchford does not start until March 2027, five months after the announcement and three months after his predecessor, Guus Dekkers, actually retires. Most companies treat a CTO exit as an emergency and backfill under pressure. Tesco built a runway instead, and that choice says as much about the company's view of technology leadership as the hire does.
Dekkers joined Tesco in 2018, made the executive committee in 2021, and is credited with modernizing the retailer's technology estate and building the data foundations that now support its loyalty and personalization work. CEO Ken Murphy framed Blatchford's arrival as continuity rather than course correction, saying he 'has led technology, data and digital transformation at scale.' Dekkers added that he expects the team to 'continue to go from strength to strength' under Blatchford, language that reads less like a courtesy quote and more like a board that planned this handoff months in advance.
Why the gap matters more than the name
Succession planning for technology leadership usually fails in the gap, not at the announcement. A CTO leaves, a search drags on, and whoever is left behind inherits decisions with no mandate to make them. Tesco closed that gap by naming technology director Jane Mustoe as acting CTO starting in November, covering the period between Dekkers' retirement and Blatchford's arrival. That is a deliberate governance choice: someone with full authority and context sits in the chair the entire time, rather than a committee or an interim brought in from outside who needs months just to learn the estate.
For CIOs watching their own bench strength, the lesson is structural. A five-month notice period only works if there is a Mustoe already in the building, someone senior enough to run the function credibly without being the permanent answer. Boards that wait until a CTO resigns to ask who could cover the gap are choosing between a rushed search and an unprepared caretaker. Tesco's version, naming the next leader early and the bridge leader explicitly, removes both bad options at once.
What Blatchford brings across the aisle
Blatchford's current remit at Kingfisher spans technology, data, and product platforms across B&Q, Screwfix, Castorama, and Brico Depot, a multi-banner structure not far removed from Tesco's own mix of formats and geographies. Tesco's announcement highlighted his record driving digital transformation, modernizing technology platforms, and applying data and emerging technology to improve experiences for both customers and staff, language that maps directly onto what Dekkers built. This is not a bet on unproven potential. It is a hire of someone who has already run a comparable-scale, multi-format technology organization and can be expected to recognize Tesco's problems on sight.
Blatchford himself struck a similarly grounded tone, saying there are 'so many opportunities for technology to improve the experience for customers and colleagues' and that he looks forward to building on the team's existing momentum. Neither Tesco's statement nor Blatchford's own comments gestured at a reinvention. That restraint is itself informative: this is a board buying execution continuity at a moment when grocery retail competition is increasingly won or lost on data and digital operations, not a board signaling it wants its technology function rebuilt from scratch.
The talent market retailers are actually competing in
A decade ago, a move like this would have been framed as poaching. Today it barely registers as unusual, because the pool of executives who have run technology at scale across multiple retail formats is small enough that competitors are the most logical source of candidates. Kingfisher's loss is Tesco's gain, and the reverse will eventually be true somewhere else. CIOs building their own succession plans should assume their most senior technology leaders are visible to, and reachable by, direct competitors running similar estates, not just adjacent industries or vendor alumni networks.
That visibility cuts both ways. It means retention conversations with a CTO or senior technology leader now have to account for a market that watches comparable companies closely, not just a generic executive search pool. It also means the retailers that build the strongest internal bench, people like Mustoe who can credibly run the function on short notice, protect themselves twice: once against the departure itself, and once against the pressure to accept a rushed external hire out of necessity rather than conviction.
The decision this leaves for other boards
Strip away the specific names and Tesco's move is a case study in a decision every board with a technology-dependent business eventually faces: whether succession planning is a document that gets dusted off during a crisis or a live process that produces a known next leader and a known bridge leader before either is needed. Tesco chose the second path, and the five-month runway is the visible evidence of that choice having been made well before October's announcement.
For CTOs and CIOs reading this from the outside, the actionable question is not whether your company could name a successor tomorrow. It is whether, if your current technology chief left tonight, there is already someone in the building who could run the function credibly for five months without a title change. Tesco's answer was yes, and that is the real story behind an appointment that otherwise reads as a routine executive hire between two large UK retailers.
