What's happened
Lidl GB has overtaken Morrisons to become the UK’s fifth largest grocer, with market share rising to 8.6% and sales up about 8.8% year on year in the 12 weeks to mid-May. The growth places Lidl behind Tesco, Sainsbury’s, Asda, and Aldi, and follows a broader trend of discounters gaining share as households seek value amid inflation. Ocado remains fastest growing online; Tesco and Sainsbury’s continue to gain share.
What's behind the headline?
What this means for shoppers

- Online growth remains strongest at Ocado, but its share is small relative to brick-and-mortar retailers.

- Large chains with strong loyalty programmes gain the most from sustained price-focused competition.
- Suppliers may face continued price pressure as retailers compete on cost leadership.
