The comments by the Prince of Wales were made during his tour of Canada when he spoke to a woman who fled the Nazis and lost family members during the Holocaust.Marienne Ferguson, 78, told the Prince that she fled to Canada with her family shortly before the Nazis annexed the Baltic coastal Free City of Gdansk in 1939.After meeting Charles, Mrs Ferguson said: "The Prince said, 'And now Putin is doing just about the same as Hitler'."I must say that I agree with him and am sure a lot of people do. But I was very surprised that he made the comment as I know they (members of the Royal Family) aren't meant to say these things."I told the Prince that while my family and I were lucky to get a permit to travel, many members of my relatives had permits but were unable to get out before the war broke out on 1 September."They were sent to the concentration camps and died."Charles' comments come amid growing international anger from the West after Putin annexed Crimea from Ukraine in March.A statement from Clarence House said it would not comment on "private conversations".It continued: "But we would like to stress that the Prince of Wales would not seek to make a public political statement during a private conversation."
