Tesco is the UK’s least favourite grocer, a new survey has found.

In the latest blow to the troubled supermarket, Tesco ranked at the bottom of a list of eight grocery chains that included, in ascending order, the Co-operative, Asda, Morrisons, Sainsbury’s, Aldi, Marks and Spencer and Waitrose in the top spot.

The consumer insights firm Market Force Information asked 6,800 British shoppers about their purchasing habits and compiled a loyalty score for each supermarket brand based on customers’ satisfaction and their likelihood to refer that store to others.
