Sir John Curtice, Britain's most famous polling expert and stalwart of BBC election nights, is at risk of becoming a national treasure. Here he offers his insights into the fragmentation of British politics; the rise of Reform under Farage and of the Greens under Polanksi; the challenges facing Labour and the Tories; the unpopularity of Sir Keir Starmer and British political leaders in general; the key requirements of leadership; the impact of culture wars on voting trends; the role of social media in shaping voters' priorities, and the effect of polling on the political landscape. Plus, Sir John reveals what he loves to do when he isn't analysing politics and polls.
