Struggling high street retailer Marks and Spencer Plc is mulling a shake-up of its food operations to coincide with the appointment of former Asda executive Justin King as head of the section. A company spokeswoman stressed to The Independent newspaper that, "in terms of how he [King] wants to run the business, it is very early days." She added however that, "with a business this size and with so many changes you can never say never."
