Throughout the weekend, we will have a special programme of informal conversations between Battle of Ideas speakers on topics in the news.
Hot off the press debates are full-length sessions.
Battle bites are short lunchtime discussions - grab a sandwich and join the debate.
All these special topical sessions are free and open to non ticket holders.
