Soccer giants Manchester United and 10 other companies including the Football Association on Thursday were facing fines of up to £300 million in total amid allegations they fixed the price of Umbro replica soccer kits.

The Office of Fair Trading (OFT) claimed today the Premiership club and its fellow accused have flouted UK competition laws that carries a penalty of up to 10 per cent of a firm's turnover.

The other companies charged are Debenhams, Umbro Holdings Limited, JJB Sports, John David Sports, Sports Soccer Limited, Allsports and Blacks Leisure, as well as Florence Clothiers and Sportsetail.

The OFT probe was launched last summer amid claims the price of replica kits was fixed. Full kits often cost up to £70 and with teams often changing their strips every couple of years, consumer groups have often complained their prices are too high.

The competition watchdog says it is now awaiting representations from the accused and will make a final decision on the matter this autumn.
