Lidl is named Britain's 'cheapest supermarket' for essentials while Tesco is the dearest for an ELEVENTH week running

Lidl's eight-item basket cost £12.97, just below Asda's £13.03. Aldi fell to third at £13.09 after its cheapest beef mince rose by 10p, a move Sainsbury's also made. Morrisons came fourth at £13.17, Sainsbury's fifth at £13.33 and Tesco last at £13.36. Shelf prices are running 2.5 per cent above last year's levels.

Lidl has held the cheapest spot in every week's comparison dating back to late August.

Aldi pushed back, pointing out that Which? has ranked it Britain's cheapest supermarket for five consecutive years.
