why I believe the Royal family murdered Dodi and Diana

Dodi was the son of Al Fiad the owner of Harrods the most famous store in the World next to Tifanis back in the seventies there was a buy out and the two main contenders were Tiny Rowland the Queens family and Al Fiad friend and family from Katar
Tiny Rowland tried to smear Al Fiad but Al Fiad counteracted with the truth about Tiny Rowland and reported that he was already done for fraud and theft in parts of Africa at that time the internet was not properly developed so it was easier to hide information like that Al Fiad divulged the information and in doing so managed to take control of Harrods .I believe that the Queen has held the Grudge against AlFiad since then and when Dodi started afairs with Diana was a perfect means for the Queen to solve both her problems in one go . Who said that she was a nice old lady?
