Marks & Spencer has been voted the UK's favourite in-store supermarket despite a strong showing from discounters Aldi and Lidl as consumers face up to the cost-of-living crisis.
The high street stalwart's upscale food offering received a customer score of 78% in the annual Which? survey, receiving five stars for store appearance, customer service and the quality of its own-brand and fresh products.
Last year's top scorer Aldi was narrowly pipped to the post with a 77% customer score, and was the only supermarket to get a full five stars for value for money.
