Price rises at budget retailer Lidl mean the cost of the same essentials has topped £11 at every supermarket.
Our weekly comparison has been tracking the cost of the same eight items since March - a two-pint bottle of milk, a loaf of bread, coffee, teabags, butter, beans, chicken breasts and mince.
Last week we reported how Lidl was the only one of the six supermarkets where the bill was still under £11, at £10.92.
