Retailer Bonmarche has seen shares almost halve in value after the group warned it could slip to a full-year loss of up to £4 million.

It follows "extremely poor" Black Friday sales and ongoing subdued shopper demand amid Brexit uncertainty.

It said: "Sales have not recovered since Black Friday, despite the application of extensive discounts. Consequently, we have concluded that sales will not recover to normal levels in the short term, and that it is appropriate to make a further revision to the forecast.

"We believe that uncertainty surrounding Brexit is a significant factor affecting demand and, therefore, that it may not strengthen until the current period of heightened uncertainty ends."
