"It is about keeping the truth alive, guarding against prejudice in all its forms and above all, showing respect to those who were killed and those who survived"
The Prime Minister has given a message on Holocaust memorial day.
Mr Cameron said:
Last year I had the privilege of meeting an extraordinary, courageous woman.
Trude Levi was just twenty when she was ripped from her family.
She was forced on a journey that can only be described as hellish, through concentration camps, work camps and death marches.
She saw and suffered some unspeakably evil things, but she survived to tell her story and pass it on to the next generation.
It is so important that stories like Trude’s continue to be heard, and read, and spoken about.
That way the brutal truth of the Holocaust can never be dimmed.
And that is why Holocaust Memorial Day matters so much.
It is about keeping the truth alive, guarding against prejudice in all its forms and above all, showing respect to those who were killed and those who survived.
And as we reflect on this part of our history - and all the millions killed through genocide - we must not forget the persecution and hatred that exist today.
We’ve got to learn from the past to improve the ways things are now.
As Trude said, we must “remember the beauty of this world and ensure we do everything we can to safeguard it.
So I want to thank everyone involved in marking Holocaust Memorial Day, not just for keeping those memories alive, but for building a better future.
