WHSmith is to extend its trial to scrap free plastic bags to other parts of the UK after a successful pilot in the Midlands and the Northwest.
Stores in the Southwest and South Wales are expected to follow suit by the end of the month and it is possible that the scheme will be rolled out nationwide.
Customers shopping in participating stores will be charged 1p for each bag they use.
The retailer said it is part of its “Think Twice” scheme, which donates money to tree projects every time a customer uses their own bag.
Other retailers to charge for plastic bags include Marks & Spencer, Aldi, Lidl and Netto.
