In 2020, Lidl were crowned the UK's cheapest supermarket by consumer website Which? who said that shoppers could save more than £20 by shopping with them.
However in updated news, the comparison website has now crowned a new winner - and it's not Tesco or Asda.
Announcing the champion on Facebook, they said that the title had now been handed over to Aldi as it was the most frequent winner of the cheapest supermarket title during the 12 months of price comparisons from January to December 2021.
Discussing it on their website, Which? stated that Aldi had just beaten their competitor who had won it the previous year and that both budget supermarkets are "consistently very close in our monthly basket comparison".
As well as comparing baskets ad the price of their own brand food, the consumer site said that "the cost of a basket of 19 items – including bread, milk and tea bags – rose by an average of 3.4% between January and December 2021."
They add: "Unfortunately, the worst could be yet to come with several big food and drink companies, including P&G, Kraft Heinz, Mondelez, General Mills and Colgate-Palmolive, warning they are preparing to increase prices.
Ele Clark, Which? retail editor, said: "No one wants to overpay for basic groceries, especially when a cost of living crunch is putting extra pressure on household budgets.
"Our findings show that, while prices are going up, some supermarkets are passing their rising costs onto shoppers more than others. As well as choosing a supermarket that is cheap overall, other ways to save include swapping from branded to own-brand products, sticking to a shopping list and resisting the temptation to pick up special offers you don’t need."

In addition to finding out the cheapest, they also looked at the most expensive.
Coming in at the top spot for every month of 2021 is Waitrose which is said to have the "unenviable title of being the priciest supermarket".
