The Co-op is set to create 250 jobs as part of a £15 million investment strategy planned for Yorkshire over the next year.
Ten new food stores have been announced in the area, including sites in York, Harrogate and Northowram.
A further 11 stores are also set to receive major upgrades, including extensions on existing stores in Thirsk, Helmsley and Sheffield.
The regional expansion comes as part of the grocer’s plan to open over 100 stores this year across the UK and follows a £50 million investment programme aimed at cutting the cost of everyday items.
“We’re delighted to be making such a significant investment in the region again in 2018, investing in our people, stores, products, prices and communities with over 20 new or improved stores this year,” divisional managing director John McNeill said.
“Such sustained investment is indicative of our long and proud history in Yorkshire – we are passionate about serving the many diverse communities across the county and want to give shoppers the opportunity to buy what they want, when and where they want it, in great looking stores that also give back to the communities that they serve.”
