The International Cricket Council has decided to ban countries from appointing politicians to national boards, vowing to free the sport from undue government influence.
After a four day meeting in Hong Kong, the ICC agreed that all member boards should be given two years, until June 2013, to get things in order.
The reform, which allows the ICC to suspend a member country in the event of government interference, will be hugely controversial in Pakistan, where the president is the cricket board's patron. Sri Lanka and Bangladesh will also be hit by the change.
The Pakistan Board has already sent a legal notice to the ICC on the amendment, and has threatened legal action if the constitution is changed.
