Waitrose is to open its first store in North Wales in Spring 2010.
The supermarket will take over the site in Menai Bridge, which is currently run by The Co-operative.
No jobs are expected to be lost when the Co-operative moves to the former Somerfield site in Llanfairpwll and Waitrose is set to take on 60 extra staff when it begins trading.
The Co-Op was ordered by the Office of Fair Trading to sell the Menai Bridge store or its Somerfield shop in Llanfairpwll, following the Co-Op’s acquisition of Somerfield this year.
