Mothercare shares slumped by 15% to 85p, their worst level for three years, and just a quarter of the value of 18 months ago. The British sales dip compared with over-optimistic internal projections that sales would grow by 3%-4% in the key Christmas quarter. 'Clearly forecasting is an area I'm putting a huge amount of effort into,' said Gordon. At the heart of Mothercare's immediate problems is its new warehouse in Daventry, which has led to a catalogue of logistics and product availability problems. The warehouse is run by Tibbett & Britten.
