The Prince of Wales has told of his pride at his "amazing" grandmother, who saved the lives of a Jewish family by sheltering them from Nazis during the Second World War.

The Prince, who first visited his paternal grandmother's grave in Israel last year, told how he took flowers from his garden in Birkhall for the deeply moving visit.

He and his wife, the Duchess of Cornwall, spent the morning with Holocaust survivors at the Jewish Museum in Vienna, during the final leg of their nine-day tour of Europe.

They included Auschwitz survivor Freddie Knoller, now 95, Gerda Frei, 80, and Harry Bibring, 91, who escaped on the Kindertransport after his family shop was destroyed in Kristallnacht.

After asking for their stories over a cup of tea, the Prince told the group of his grandmother's own experience, loyalty and heroics during the war.
