“His external experience with the Catapults and Made Smarter programme will also be a real asset.
“Brian will build on the strong foundations already in place, continuing to focus on the areas where we can make the greatest difference and create more value for customers.
“This will become even more important as we take forward our ONE Tech Company programme and ensure we serve our customers in a seamless and straightforward way.”
