Its origins date back to a group of Yorkshire farmers in the 1920s. Nowadays, Asda is better known for its 'rollback' reductions, pocket-tapping jingles and promises of low prices.
It's owned by US retail giant Walmart, and has more than 600 UK stores. But how does Asda stack up against the other supermarkets?

Asda in the news
The Competition and Markets Authority blocked plans for Asda to merge with rival Sainsbury’s in spring 2019. It said the proposed merger would have led to higher prices and reduced range and quality. Collectively, they would have overtaken Tesco to form the biggest supermarket chain in the UK.
In February 2020, Asda's owner Walmart said it could sell a majority stake in Asda but would not comment further.
In April 2019, we investigated how much of supermarket plastic packaging is recyclable. You can find out how Asda compared to other supermarkets in supermarket plastic packaging.
