Results from traditional supermarkets Sainsbury's (>> J Sainsbury plc) and Morrisons (>> WM Morrison Supermarkets PLC) suggest that Britain's supermarkets enjoyed strong trading over Christmas, while market leader Tesco (>> Tesco PLC) is expected to do well when it reports on Thursday.

Lidl UK, which alongside Aldi has shaken up the market in recent years due to its ultra low prices, said in 2017 it would remain "absolutely focused" on saving customers more money, and would stick to its ongoing expansion plan.
