It is understood that the cost of any job losses would be absorbed by the savings made by reorganising staff.
The retailer announced a cost cutting review of the business in April, followed by a fall in like-for-like sales of 8.8 per cent in the two months to the beginning of May.
Shore Capital analyst John Stevenson said he expected like-for-like sales to decline over the first half of the financial year by about 5 per cent to 6 per cent, against strong comparables in the previous year. He acknowledged the commitment to structural efficiencies, but doubted the retailer would gain any benefits in the short term.
He said: 'We are mindful of the consistent improvements that the management team continues to make to the business, in terms of stores, range, processes and supply chain. Unfortunately in the current market conditions, we suspect it may be some time before the benefits of such actions become more apparent.'
