Russian president Vladimir Putin has described the Prince of Wales's reported comparison of him with Adolf Hitler as "unacceptable" and "wrong" and said that remarks of this kind are "not what monarchs do".
Mr Putin's response came just days after the prince was reported to have made the remark in a private conversation during his visit to Canada.
The Russian president was asked for his response by Press Association chief executive Clive Marshall during an interview with the world's leading news agencies in St Petersburg.
Mr Putin said: "It reminds me of a good proverb: 'You are angry. That means you are wrong.'"
In a direct personal message to the Prince, he added: "Give my words to Prince Charles. He has been to our country more than once, if he made such a comparison, it is unacceptable and I am sure he understands that as a man of manners."

Mr Putin added: "I met him personally, as well as other members of the Royal Family. This is not what monarchs do.
"But over the past few years we have seen so much, nothing surprises me any longer."
Charles's comments were reportedly made to Canadian museum volunteer Marianne Ferguson, 78, after she told him how her Jewish family fled the Nazi occupation of Danzig at the outset of the Second World War, and appeared to draw a parallel with Russia's annexation of the Ukrainian peninsula of Crimea in March.
The Russian president made clear that he would not allow the disapproval of prominent international figures such as the Prince of Wales to influence his actions in the current crisis in Ukraine.
"I will be guided not by what they say about me anywhere," he said.
"I will only be guided by the interests of the Russian people, and I hope our colleagues in Great Britain will keep that in mind and will always remember that when finding solutions to any issues, we are always guided by international law and its norms."
