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.
Big Data, big danger?
"Five debates a day sounds a bit daunting beforehand, but I really loved it. The speakers are so knowledgeable and passionate about their chosen topic, and the amount of time dedicated to questions from the audience was great as it really brought in alternative views."
