Sales fell by 1.4 per cent at John Lewis during the first week of March, with the retailer citing unseasonable weather, Mother's Day and televised sporting events for the slip.
According to the John Lewis Partnership, sales at its department store division were £46.9 million.
However, despite the fall in sales, its award winning electricals and home technology department continued to thrive, performing better than the same time last year despite a falling economy.
According to John Lewis' personnel director, Eric Gregory, the majority of the dip was due to Mothering Sunday. Sales were up during the first six days of the trading week; however, it was "not enough to compensate for the shortfall on Sunday," he told Retail Week.
