it seems to me they might not release the information if the test showed charles wasn't the father.
Sometime around 1776 my family showed they no longer gave a tinkers dam about the royal snoots. We have always named our dogs Duke, Queenie, Prince, King and Princess. I now see why.
The tests showed that both princes had been fathered by Charles, the heir to the British throne, who Diana finally divorced in 1996, a year before her death in a Paris car crash.
However...
Some other British newspapers have ridiculed Simmons' supposed revelations, saying she was never especially close to Diana and is most likely inventing stories for financial gain.
