Chinese dissident Wu’er Kaixi, a student leader during the pro-democracy protests in 1989, takes part in a live debate on democracy with Stephen Sackur. The year 2015 marks 750 years since the first Westminster parliament and 800 years since the sealing of Magna Carta. These landmark moments underpinned the establishment of Parliamentary democracy and the legal system in the UK and around the world. The BBC's Democracy Day will look at democracy past and present and encourage a debate about the future of democracy. How democratic are we?
