Cheapest supermarkets for Christmas dinner named - and the winner isn't Aldi or Lidl

There are three major supermarkets that are cheaper to buy your Christmas Dinner ingredients from than than Aldi or Lidl.

That's according to a new study by discount site Savoo, which took the same shopping list to the nine biggest supermarket chains then compared costs.

Asda was found to be cheapest - coming in at less than half the price of rivals like Waitrose and Marks & Spencer.

After Asda, Sainsbury's was the surpising result for the second-cheapest place to shop, followed by Iceland, Lidl and Aldi.

Savoo managing director Ed Fleming said: "It’s crucial for families to consider all their outgoings in the weeks building up to the 25th December, with food being a key element."
