Prince Harry has spoken out over rumours that King Charles is not his real father. The publication of his book Spare has included a number of explosive revelations which have rocked the Royal Family.

And in one extract of the book, the Duke of Sussex addresses rumours that his dad is actually Major James Hewitt. In an extract, as seen in Page Six : Harry says: "Pa [King Charles] liked telling stories, and this was one of the best in his repertoire. He’d always end with a burst of philosophising… Who knows if I’m really the Prince of Wales? Who knows if I’m even your real father?

"He’d laugh and laugh, though it was a remarkably unfunny joke, given the rumour circulating just then that my actual father was one of Mummy’s former lovers: Major James Hewitt. One cause of this rumour was Major Hewitt’s flaming ginger hair, but another cause was sadism."

He added: "Never mind that my mother didn’t meet Major Hewitt until long after I was born." Harry also writes in his memoir that he killed 25 people while serving in Afghanistan.

He writes: "Most soldiers don't know exactly how many kills they have to their credit. Under battle conditions, you often fire indiscriminately. However, in the age of Apaches and laptops, everything I did in the course of two tours of duty was recorded and time-stamped.

"I could always tell exactly how many enemy combatants I had killed. And it seemed essential for me not to be afraid of that figure. Among the many things I learned in the Armed Forces, one of the most important was to be accountable for my own actions."

He continued: "So my number: twenty-five. It was not something that filled me with satisfaction, but I was not ashamed either.

"Naturally, I would have preferred not to have that figure on my military resume, or in my head, but I would also have preferred to live in a world without the Taliban, a world without war. However, even for a casual practitioner of wishful thinking like myself, there are realities that cannot be changed."
