Leeds United face revealing the identity of their owners if they win promotion to the Premier League this season.
The league's chief executive, Richard Scudamore, said they will apply the rules on ownership transparency more strictly than the Football League have done.
Scudamore told the culture, media and sport committee: "The Football League have chosen not to apply the rule as robustly as we think we will be applying it.
"The Football League have one view of how to interpret that rule and we have a more stern or harsh view of what the rule means.
"Our clubs absolutely agree unanimously that we should tell the public who owns the clubs and anything short of that is inadequate.
"If it arises, if Leeds United on sporting merit deserves to be in the Premier League, we will do all we can to persuade them to stay within the rules."
