Britain's retailers enjoyed an even busier day yesterday in their post-Christmas sales after reporting their biggest day of the year on Monday as bargain hunters continued to flock to the high street. Many retailers and shopping centres reported record crowds in search of big price reductions, but these are unlikely to help the profits of an industry that saw lacklustre trading in the run-up to Christmas, analysts said. Some companies may have to make profit warnings, they said. Most British retailers kicked off their seasonal winter sales on Monday with many big chains cutting their prices by 30-50 percent to attract bargain hunters, and generally reported a bumper start to the season. Europe's biggest shopping centre, Bluewater in Dartford in Kent, said yesterday was its busiest day of the year, topping the record crowds seen on Monday. Yesterday was busy, but today is busier. We had 130'000 visitors on Monday but today will be over 140'000, said Bluewater spokesman David Robinson. The centre on the outskirts of south-east London, which boasts Marks and Spencer, John Lewis and House of Fraser stores, saw particularly good business from men's and women's fashion clothing and electronics goods.
