Yes. Whether you are successful or not in the West Midlands Ballot, you will still be able to apply for further tickets in the Main Ballot in September.
However, there are limits to the number of tickets you can buy for each session. If you are successful in the West Midlands Ballot and receive the maximum number of tickets for a particular session, you won’t be able to apply for more tickets for that session. You will be able to apply for any other session for which the ticket limit hasn’t been reached.
