Prince Philip and Queen Elizabeth have been married for over seven decades. And they have been blessed with four children.

But on the online forum site Quora, one royal fan asked an absurd question that angered the other participants. The fan wondered if it’s true that the Duke of Edinburgh only met the Queen two years after Prince Charles was born. If this is the case, Prince Philip couldn’t have been Prince Charles’ father.

Mike Wright, a graduate from Cambridge University, sarcastically responded to the question. He said that the rumors are true because the man that Her Majesty married in 1947 was just a lookalike of the retired royal.

“Charles true father was -as is well known in Royal Circles - the then British Home Secretary, Mr. James Chuter Ede. There are some deluded American conspiracy theorists who think that Charles was actually conceived by artificial insemination, the donor being US President Harry S. Truman. But these claims can be discounted. There is no serious doubt as to Mr. Chuter Ede being the father,” he said.

Kate Boulton, who works at VHR, said that a very quick online search could have given the royal fan the answer that she was looking for. And this would’ve prevented her from asking the question on Quora.

“Not only that, but the inference behind the question is insulting to Queen Elizabeth and actually libelous,” she said.

Brian Davis, a retired banker, gave a similar response. She said that the question borders on being absurd because Prince Charles was born one year after Prince Philip and the Queen tied the knot.

“One must wonder who sired Prince Charles if they hadn’t met until two years after Charles’ birth,” he said.

And Lorraine Houston, a former student at Durham University, dubbed the question as complete rubbish. She also said that the Queen and Prince Philip have known each other since the former was 13 years old, and there’s footage to prove that this is the case.
