Who is Mark Dryer?
Mark Dyer is a former Welsh Guards officer. He was a royal equerry and served Prince Charles until the mid-1990s. He was educated at Cheltenham College and one of his nicknames is Marko. It is said he became a mentor for Prince Harry and Prince William after Princess Diana died.
Did Prince Harry have a DNA test?
However, no paternity test has been undertaken and there is no evidence that Harry is not a Windsor. Anderson's book however is still stoking the rumours ten years on, he names witnesses who in fact say Diana and Hewitt were lovers before, not after, Harry was born.
