Sports goods chain JJB Sports has reported further sales decreases, attributing the bad performance to a difficult trading environment and an absence of large-scale sports tournaments.

JJB said sales figures for late April and May showed double-digit percentage drops, with the 16-week period ended 22 May recording a 7.7 per cent fall in total.

The retailer had previous referred to "challenging" conditions in April, with a 1.3 per cent same-store sales decrease for the 10-week period ended 10 Aoril.

2004 performance was helped by replica football kit sales during the Euro 2004 tournament, the company said, and added that it hoped to see similar results during the 2006 World Cup.
