Iain Duncan Smith has written movingly today on ConservativeHome about the Holocaust Educational Trust-sponsored trip to Auschwitz which he, I and others joined a week ago.
It is quite a harrowing experience and helps you to comprehend the sheer scale of mass extermination undertaken by an evil regime which was in power in Europe during my grandparents' lifetime.
And it is a timely lesson that the Nazi ideology which resulted in the mass murder of Jews, Romany Gypsies and others is the very same ideology subscribed to by the British National Party.
BNP leader Nick Griffin has spoken chillingly about his "final vision" of a "genetically white country" and is, of course, also on record as having denied the Holocaust, despicably describing it as "the hoax of the 20th century".
All the more reason to remember that there is nothing British about the BNP.
