Several Spar shops across Cumbria remain closed today due to a cyber attack.
Stores had to close on Sunday following the UK-wide attack on its IT systems which affected their ability to process card payments.
It is thought more than 300 Spars in the north of England are affected, including those in Workington, Keswick and Penrith.
Keswick’s Shorley Lane store did not close, but was accepting cash only after its tills went down.
The website for Preston food distributor James Hall and Co, which sends goods to nearly 600 Spar shops throughout the north of England, crashed on Sunday.
A Spar spokesman said: “At James Hall we are currently aware of an online attack on our IT systems.
“This has affected around 330 Spar stores across the north of England and we are working to resolve this situation as quickly as possible.
“It is currently impacting stores’ ability to process card payments meaning that a number of Spar stores are currently closed to shoppers or only taking cash payments.”
