This week, I signed the Holocaust Educational Trust’s Book of Commitment ahead of next week’s Holocaust Memorial Day. The 27th of January will mark the 80th anniversary of the liberation of Auschwitz concentration camp. 80 years on, we will remember all those murdered by the Nazis and pay tribute to the remarkable survivors. In their name, we pledge to keep fighting hatred, prejudice, and racism today, wherever these things are happening. It is absolutely vital that politicians who make these pledges are held to them.
