In this live final hosted by Claudia Winkleman and Nick Robinson, the celebrity advocates return to fight their winning icon's case, and the public vote for the person they think was the greatest figure of the 20th century. Who will the greatest icon be? Voting opens near the start of the programme and there will be two ways to cast your vote: by telephone (details are outlined during the final) or via the series website. The winner is announced at the end of the final.
