Police confirmed today that the weather-related death toll had risen to 26. A 90-year-old woman froze to death in her garden near Barnsley after falling in the snow. Widow Mary Priestland was discovered when her neighbour called round to make her tea. A 42-year-old Newcastle woman died after being found lying in the snow this morning. She had told her family she was going for a walk at 7pm on Friday.

　　Concerns have now switched to food supply. Sub-zero temperatures have made it impossible to extract some vegetables from the ground. Producers of brussels sprouts and cabbages are all reporting problems with harvesting. Cauliflowers are said to have turned to "mush" in the sustained frost, with the result that only imported ones are available – at more than £2 each.

　　"Food is selling fast and there is a problem with replenishing it," said Stephen Alambritis of the Federation of Small Businesses. "One business I spoke to said it was like Christmas Eve, with people rushing to buy up food. This will inevitably have an impact on food prices."

　　Food prices had already started to edge up after a sustained period of low inflation. Food inflation increased by 3.7% in December, up from 2.8% in November, said the British Retail Consortium.

　　In Ireland, 6,000 acres of potatoes remains unharvested and there are claims that up to three-quarters of the crop may be ruined. Potato growers in Northern Ireland say they are facing some of the biggest losses in recent history because of frost damage.
