At the moment, the website states:
The Secretary of State for Culture, Media and Sport, James Purnell, has rejected applications to join the exempted ‘white list’ from Alexander (Canadian Reservation), Netherlands Antilles and Tasmania. Applications from Kahnawake and Antigua are still being considered.
Gambling operators in jurisdictions that did not apply to be white listed are also automatically banned from 1st September too. These include major online gambling centres like Costa Rica and Belize.
Only Alderney and the Isle of Man were able to demonstrate that they had in place a rigorous licensing regime designed to stop children gambling, protect vulnerable people, keep games fair and keep out crime.
Countries in the EEA did not have to apply to be white listed.
