Britain's cheapest supermarket is revealed by watchdog after stealing crown from budget retailer

Britain's cheapest supermarket for November has been revealed by consumer watchdog Which?. 

The organisation has revealed that Aldi has taken the top spot as the UK's best budget retailer, stealing the crown from fellow German supermarket Lidl. 

Which? compared the prices of 47 popular grocery items such as potatoes, chicken and milk, every day last month, revealing their average costs at each of the UK's biggest supermarkets. 

Aldi was the cheapest overall, with the items costing £76.77 on average, while Lidl was just 79p behind, with an average cost of £77.56. 

It comes after Lidl stole the title of cheapest supermarket from Aldi in October, ending its 16 month stint at the top of the list. 

Which? compared the prices across the UK's eight biggest supermarkets, including Lidl and Aldi, with the 47 items costing almost £100 on average at the priciest retailer. 

According to the analysis, Asda ranked third, with an average cost of £82.42, with Tesco's basket cost of £87.42 landed it in fourth place. 

Sainbury's was narrowly behind it with an average basket of £87.79, while Morrisons came in sixth with its basket costing £89.54 on average. 

Which? found that Ocado and Waitrose were the UK's most expensive supermarkets with a basket costing £93.40 and £97.39 on average, respectively. 

The consumer champion also compared the cost of a larger trolley of 134 items, which included the original 47 as well as more branded groceries. 

Aldi and Lidl weren't included in the analysis as they don't always stock branded products. 

Asda was the cheapest for this larger trolley at £328.15, more than £10 less than its rival Morrisons, which was the next cheapest at £338.16.

Following behind was Tesco at £354.53, Ocado at £356.78 and Sainsbury's at £360.26.  Waitrose was most expensive at £369.80. 

Which? compared the prices across the UK's eight biggest supermarkets, including Lidl and Aldi, with the 47 items costing almost £100 on average at the priciest retailer. 

The analysis includes special offer prices but not multibuys or loyalty discounts such as those offered by Sainsbury's Nectar and the Tesco Clubcard.

Which? says that this is because not all shoppers are prepared to sign up to loyalty schemes, and therefore it is fairer only to include prices available to all.

It comes as it was revealed that the cost of vegetables for Christmas dinner has soared by up to 60 per cent in one year with carrots, potatoes, parsnips and brussels sprouts all hit by soaring inflation.

Prices have risen by an average of 7 per cent over the past year across 208 lines of parsnips, carrots, potatoes and brussels sprouts at Aldi, Lidl, Co-op and Waitrose.

Data from retail research firm Assosia revealed annual price rises of at least 10 per cent on more than a third of products, while 24 increased by more than 20 per cent.

The analysis of supermarket prices revealed in trade journal The Grocer also found the cost of some vegetables had risen by more than a tenth in just the past month.

Soaring production costs and poor weather affecting growing conditions were said to be partly behind the increases, as well as low supermarket returns for many crops.
