The UK's top retailers are no longer gaining collective market share at the expense of their smaller rivals as rising competition between the leaders and pressures to de-merge non-core businesses take their toll. Instead, the new retail elite is made up of focused specialists such as Next, JJB Sports and Matalan according to Retail Knowledge Bank's newly published Top 500 - 2002. It says the Top 10's UK sales in 2001 were £1bn less than in 2000, down by 1.3 per cent. This resulted in a combined share of UK retail sales falling from 43 per cent to 41 per cent. Total UK retail sales rose by 4 per cent and £7 billion in the same period.
