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".

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 Saint Petersburg.

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."

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."

The prince'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 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."

Britain has led international calls for sanctions against Russia in response to its actions in Crimea, and last week the prime minister, David Cameron. warned that the UK may have to prepare for "a very different long-term relationship with Russia" if Moscow failed to take action to de-escalate the crisis.

But Putin indicated that he did not regard the current differences as the start of a long-lasting rift in UK-Russian relations, and said he anticipated a return to "good cooperation" if the UK decided to be guided by its own "national interests".

Putin said: "Only if we respect international law will we be able to find solutions to the most difficult issues.

"Should our British partners be guided by their national interests - like I do - and not by other reasons, I am sure this will soon become a thing of the past and we will be able to continue good cooperation like back in the days, and maybe even reach some new heights and can start thinking about what is to be done in the future in order to make our cooperation more efficient."

A spokeswoman for the prince declined to comment on Putin's criticism.
