Lidl has been named the cheapest supermarket in the UK for a third month in a row.
The monthly study carried out by Which? magazine found that a basket of 21 items at Lidl cost £28.83.
Items contained in the basket included a range of own brand products, such as eggs and apples, in addition to some branded goods.
Aldi was the second cheapest supermarket for that month, with the basket costing 31p more.
Waitrose was the most expensive in the UK, with the same group of items coming in at £36.04.
Ryan McDonnell, Lidl chief executive, said: “This is the third month running that Which? Has named Lidl as the cheapest supermarket.
“As inflation continues to rise, I want to reassure each and every one of our customers that we remain resolute in our promise of being the destination for the highest quality groceries at the lowest prices in the market.”
Asda was found to be the cheapest supermarket when an additional 44 items were added to the basket - which contained more branded items than previously.
The cost of the Asda basket was found to be £128.80, which was a whopping £20.16 cheaper than Waitrose - which was once again the most expensive of the supermarkets.
Which? Also found that grocery price inflation had soared by 5.2 per cent in March, which is the highest level since April 2012.
Earlier this week, shoppers were warned that the price of milk could soar by 50 per cent in the coming weeks and months.
The cost of petrol and diesel has also soared to record levels following the Russian invasion of Ukraine.
And the cost of living crisis in the UK deepened at the start of April after the entry price cap soared by 54 per cent.
Ofgem increased the cap by £693 to £1,971, up from the previous cap that was £1,277.
Money Saving Expert Martin lewis described the rise in the price cap as “astronomical” and “catastrophic”.
