But the outdoor retail chains Mountain Warehouse, Go Outdoors and Cotswold Outdoor are among those still thought to be interested in buying part, or all, of Blacks. The outdoor group, which has debts of £36 million, put itself up for sale last week by hiring advisers at KPMG after shareholders and potential new investors refused to back a cash call. In an accelerated process, the group has invited first-round bids before Christmas and is hoping to complete a transaction before the end of January. The company behind 98 Blacks outlets and 208 Millets stores has to refinance its debts before the start of its new financial year on 3 March.
