PwC’s India affiliate has resigned as the auditor of Carlsberg India, declining for a second year in a row to give an opinion on its financial results, the brewer and two people familiar with the matter told Reuters.

Denmark’s Carlsberg A/S has been locked in a commercial dispute with its joint venture partner in India, Nepal-based Khetan Group, amid an internal probe into the brewer’s local practices that sparked a boardroom battle and concerns from its auditor.

“The divergent views among the Carlsberg India board is the reason for the disclaimer of opinion made by the auditor,” said Steve Deng, corporate affairs director for Carlsberg Asia.
