It was an honour to sign the Holocaust Memorial Day Book of Commitment again this year, to reaffirm my steadfast commitment to remember the six million Jewish men, women and children who were brutally murdered in the most shocking and tragic of circumstances, and rightly pay tribute to the Holocaust survivors. We must never forget the lessons of those dreadful events, which are as important and relevant now as they were then. We all have a duty to call hatred out wherever we find it.
