I joined the Speaker of the House and colleagues to mark Holocaust Memorial Day with a ceremony in Portcullis House.
Lighting a candle of remembrance gave me a moment to reflect on how fragile freedom is.
We remember those who faced persecution and genocide during the Holocaust: some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population.
We recall the tragedy of the persecution of other groups that the Nazis targeted including the Roma and Sinti, homosexuals and the disabled; and recognise the genocides that followed in Cambodia, Rwanda, Bosnia, and Darfur.
We must never forget the horrors of the Holocaust.
Now more than ever, we must stand up against antisemitism and hate.
