The first detailed evidence of how Christmas has gone should come from fashion chain Next later this week ? though preliminary indications from Woolworths do not look good. Next is understood to have had a torrid Christmas and analysts have suggested that the best the chain could hope for was a 'solid' and 'acceptable' performance. Other retailer have had a far more difficult time, with serious questions raised about Marks & Spencer, House of Fraser, Allders, JJB Sports, WH Smith, Dixons, Boots, Clinton Cards, French Connection and Benetton.
