Spain's Olympic basketball players were forced to train with their shirts and shorts inside out yesterday due to a dispute over logos.

The Spaniards turned up with kit covered in the logos of team sponsors who had not paid to be part of the central Olympic sponsorship system. Olympic officials made them reverse it to hide the logos from photographers recording the open session.

Some players, seemingly in response to the Athens heat as much as the official ruling, chose to play bare-chested instead.
