Revenues at the grocer, which is part of by privately-owned German retailer Schwarz Group, rose 7.9% in the year to 28 February to £11.7bn.

Lidl - which first opened in the UK in 1994 - is due to open its 1,000th store in November. It is one of 13 new shops scheduled to open before Christmas, and 40 before the end of the current financial year.
As well as benefiting from its expanding footprint, Lidl said over £400m of turnover had come from direct switching from competitors.
Both Lidl and larger rival Aldi have enjoyed a boom in recent years, as hard-pressed shoppers seek out cheaper prices amid soaring inflation and high food prices.
According to recent data from retail consultancy NielsenIQ, sales at Lidl rose 11% in the 12 weeks to 4 October, giving it a market share of 7.8%.
Ryan McDonnell, chief executive of Lidl GB, said: "Our results reflect the momentum we’ve built and the trust shoppers place in us. More households are choosing to shop with us more often, because we continue to deliver on our promise of outstanding quality at the lowest possible prices.
"Over the last year, we have continued to operate with our discounter efficiency at the heart of everything we do."
Shore Capital said: “Lidl is a formidable player in UK grocery, and with strong ongoing execution and evolution of its offer – plus around 30 to 40 new stores per annum, alongside refurbishment work – we can envisage ongoing shares gains.”
Data from the Office for National Statistics on Wednesday showed food prices had softened in September, for the first time since May 2024. Food inflation now stands at 4.5%, off August’s 5.1% high.
