11 November is Remembrance Day in the UK, the day that the first world war ended in Europe. For too long ceremonies have remembered only the country’s own military dead, symbolised by red poppies. But gradually more and more people have worn the white poppy, the symbol of peace, in remebrance of all those, military and civilians, women and children, who have died in all wars around the world, irrespective of whose side they were on.
