Will we recognise the signs that democracy has ended? Cambridge professor David Runciman worries that we spend far too much time comparing today's politics with the 1930s, and that this blinds us to the frailties of democracy today. He tells Amol Rajan why he thinks our current political system will come to an end - and why we may not even notice this happening.

Professor Nic Cheeseman is all too aware that democracy can become an empty shell. His new book How To Rig An Election, co-written with Brian Klaas, looks at the myriad ways autocrats use elections for their own ends, from buying votes and bribing electors to issuing fake pens in the ballot box. And it is not only the developing world in which corruption takes place. He addresses the role of outside states in the 2016 US presidential election, and asks how western democracy can be kept healthy.

Anne Applebaum has studied the ways in which democracy can arise like a phoenix from the ashes of authoritarianism. As the author of Red Famine: Stalin's War On Ukraine, and a professor at the LSE, she has analysed the reasons why democracy flourished in Poland and Ukraine after 1989, and suggests reasons why the 2012 Arab Spring has not yet had the same results. But as a journalist for the Washington Post she is all too aware of attacks on democracy today, both in the former Soviet bloc and in America. She argues that the onus is on us to save our own systems.
