Karen Pollock, chief executive of the Holocaust Educational Trust, said it was an “incredible initiative”.

She added: “These Holocaust survivors endured the very worst. They were rounded up into ghettos, sent to concentration camps and enslaved as forced labourers. 

“To survive the concentration and death camps and 77 years later see their portraits displayed in Buckingham Palace is very special indeed, and a poignant and fitting testament to their lasting contribution to this country.

“The Nazis intended there to be no Jews left in Europe – instead these survivors are honoured at the heart of British society.”

“The Prince of Wales has long been a true supporter of Holocaust education and remembrance, and we could not be more grateful and indebted to him for the work he continues to do to ensure that the Holocaust holds a central place in British history and memory.”
