image Newsnight will ask its panel tonight: ” What kind of life can a chicken have had when it ends up sold at Tesco for £2?” The answer is obviously none.

It then continues to ask if anyone can afford to care when food prices are tripling and it costs nearly £75 to fill your car with petrol.

My answer to that is yes, we have to care and maintain public health standards. But at the end of the day, you will buy what you can afford. The days of cheap food have gone. Or have they? Tesco and Asda are waging a price war to entice shoppers, with Asda already selling ten staple items, including bread, eggs and butter, for only 50p from today.

I do not expect Asda is making a loss on these drastic price reductions, and if supermarkets can afford to do this now, how can they justify increasing these prices again and continuing to make vast profits at the expense of families struggling on the breadline? I appreciate that supermarkets have had to meet increased costs too, but now they must narrow their profit margin and tighten their belts just like the rest of us if they want to keep consumers on their side. I wonder if they predicted this a couple of years ago in their business plans.

Interestingly, Aldi, the German-owned discount chain, has experienced a 20 per cent rise in sales over the past four weeks – the fastest growth rate in Britain. The number of shoppers visiting its 400 stores has gone up by a quarter in the past three months. I can admit to being one of their new shoppers, though I still spent more than I wanted. Marks & Spencer, meanwhile, has suffered a 3.2 per cent fall in takings in its food halls in the past month.

So food is not just a political weapon, it’s also the cause of supermarket price wars, and this is a taste of what is to come. If you have any shopping tips on where and how to find best value, do share them please…
