Last night's meeting of the county council saw spirited, and, at times, heated debate over the council's decision last month to approve the construction of a supermarket on the site of the village car park in Hiddlesfield. Shopkeepers are particularly concerned about the loss in trade that may result from the opening of a national supermarket in a village of Hiddlesfield's size. The fishmonger suggested that the council learn the lesson of Aldersham, the neighbouring village, where the council allowed a national supermarket to be built three years ago. Within three months of the supermarket opening, half of the shops in Aldersham's high street had shut, due to the loss in foot traffic. In response, a councillor pointed out that the supermarket had brought dozens of jobs to Aldersham, along with many conveniences and products not previously available in the village. Hiddlesfield's butcher also spoke very forcefully against the supermarket. She argued that its beef and lamb are sourced from Wales and Ireland, rather than the local farms that her shop favours. The butcher said that the cost to the local economy is far greater than the potential loss of shops on the high street, when the consequences to businesses in the county at large are considered.
