Premier League clubs have voted to approve changes to rules governing commercial deals.
At a meeting in London on Friday, clubs took under 30 minutes to approve the changes to Associated Party Transaction (APT) regulations.
Clubs voted 16 in favour and four against. Those voting against included Manchester City and Aston Villa, who had both written to clubs before the meeting seeking support.
Friday's vote came after an independent panel found aspects of the Premier League's rules to be unlawful earlier this year, following a lawsuit instigated by Manchester City.
The Premier League says the rule changes relate to "integrating the assessment of shareholder loans".
"The purpose of the APT rules is to ensure clubs are not able to benefit from commercial deals or reductions in costs that are not at fair market value by virtue of relationships with associated parties."
