The English Bridge Union (EBU), which has 55,000 members, went to London's High Court to argue that Sport England, a public body that provides grants to activities to help the nation get fitter, was wrong not to classify the card game as a sport.
The EBU said that the level of physical activity involved in playing bridge was not that dissimilar to that required to playing darts.
