Premier League clubs will be required to sign up to a new Owners’ Charter with "significant sanctions" for breaches of rules in the wake of the proposed breakaway Super League.
In a statement, the Premier League said it was taking several measures to "protect our game, our clubs and their fans from further disruption and uncertainty".
They include a new "Owners’ Charter that all owners will be required to sign up to, "committing them to the core principles of the Premier League".
"Breaches of these rules and the Charter will be subject to significant sanctions," the Premier League said.
It added that is "enlisting the support of government to bring in appropriate legislation to protect football’s open pyramid, principles of sporting merit and the integrity of the football community".
