BBC Scotland leaders' debate
BBC Scotland's leaders' debate will take place on Sunday 1 May from Perth Concert Hall.
The 1,000-strong audience will put the party leaders through their paces only a few days before Scotland goes to the polls.
The debate will be hosted by Glenn Campbell.
The event has now reached full capacity and we are not allocating any more tickets.
You can tune in to watch the debate on BBC One Scotland at 2225 BST on Sunday, and it will also be streamed on the BBC Scotland news website.
