Asda (2)

Asda has said it suffered its biggest ever quarterly fall in sales over the Christmas period.

The supermarket saw sales drop 5.8% during the three month period - a huge figure when you consider Tesco and Morrisons beat forecasts and Sainsbury's suffered just a 0.4% fall.

Over the year, Asda said its sales fell 4.7%, with chief executive Andy Clarke describing 2015 as a "difficult year".

The Walmart-owned supermarket is currently focusing much more on its core prices in an attempt to win back sales and customers. In January, it announced a further £500 million investing in cutting prices, taking its total to £1.5bn. Part of its focus on core prices had seen it move away from one-off promotions, which included the Black Friday discount event in November.
