Premier League clubs have agreed to tighten rules regarding Associated Party Transactions.
The new measures, aimed at clubs doing sponsorship deals with companies that have ownership links, were voted for at Friday's Premier League shareholders' meeting in central London.
A Premier League statement read: "Following a full review of the existing Associated Party Transactions Rules and Fair Market Value assessment protocols, clubs agreed to a series of amendments to further enhance the efficiency and accuracy of the system."
It is understood the vote was not unanimous. Manchester City have previously expressed their opposition to the rule changes.
Premier League clubs voted against a similar motion for more stringent rules at a shareholders' meeting in November.
