As we mark Yom Hashoah, my thoughts are with Jewish families here in Britain and all around the world.
I will never forget that chilling moment in January, when I stood with my wife in Block 27 of Auschwitz, searching for members of her family in the Book of Names. We turned page after page after page just to find the first letter of a name. It was utterly harrowing.
Today, Jewish people stand together to mourn the loss of every one of those six million victims, and to honour the breathtaking courage of those who resisted the Nazis, including in the extraordinary Warsaw Ghetto Uprising.
As prime minister, I want you to know that you do not stand alone; you do not remember alone; and you do not carry forward the educational legacy of our inspiring Holocaust survivors alone. The duty to remember the Holocaust, to fight the poison of antisemitism and to educate future generations is a duty for us all.
