In this week's Spectator Books, Sam is joined by Deborah Lipstadt -- the historian who herself made a piece of history when she defeated the Holocaust denier David Irving in court. In her new book Antisemitism Now, Professor Lipstadt returns to the fray to look at the worldwide uptick of antisemitism in our own day and age. Sam asks her why she felt the need to write this book and frame it in the way she did, how antisemitism differs from other forms of prejudice, and what you can and can't say about Israel. 

Presented by Sam Leith.
