The British arm of German discount supermarket operator Lidl on Friday reported an 8% year-on-year rise in sales for the six weeks to 30 December boosted by strong demand for its premium products.
Lidl also said it was committed to investing a further £1.45 billion ($1.85 billion) in 2019 and 2020 in Britain where it ranks seventh among supermarkets with 730 stores.
Like discounter rival Aldi, Lidl has been opening stores aggressively which is helping it gain market share from Britain's big four grocers - Tesco, Sainsbury's, Asda and Morrisons.
Discounters' Product Innovation
But consumers are also being attracted by the discounters' product innovation.
On Monday Aldi said its December sales increased by around 10% to almost £1 billion and highlighted increased demand for premium products.
Lidl UK said sales of its premium Deluxe range were up 33% year on year. It cited premium cooked crisps, mince pies and brioche burger buns as top sellers.
