Sports Direct has called for a Europe-wide investigation into the dominance of Nike and Adidas in the sportswear market.
The firm said the “must-have” brands hold a bargaining position which allows them to control both the supply and the price of their products.
Adidas has blocked the company from selling some of its products, Sports Direct said in a statement.
It follows reports that Nike is ending supply deals with several retailers.
“Sports Direct believes that the industry as a whole would benefit from a wide market review by the appropriate authorities in both the UK and Europe,” it said in a statement.
