Mr Baddiel, whose mother was a refugee of Nazi Germany, has described himself as a “Jewish atheist”. The north Londoner said: “As the last survivors, including those in my own family, begin to pass away, and with them, living memory of The Holocaust, I’m grateful to the BBC for allowing me to explore this complex subject, in all its difficulty and darkness.” Want the best of The Telegraph direct to your email and WhatsApp?
