Rumors on Princess Diana's pregnancy couldn't be confirmed due to the refusal of the British royals to exhume her body.
Lady Di was embalmed on the orders of British authorities to prevent all tests, which could have established whether or not she was carrying her lover's child.
According to British newspaper the Daily Express, a top official at the British embassy in Paris was informed just minutes after the Princess's death that embalming her body would be illegal. The procedure went ahead anyway.
"Nobody should be embalmed before a post-mortem. There is no reason why this should have been done in the case of the Princess", Professor Peter Vaneziz, an independent pathologist stated.
"There was no reason for it to be done in order to repatriate her body to this country. That is evidenced by the fact that Dodi Fayed's body was not embalmed.
One would have normally thought that the effect of embalming would destroy body samples if the person was pregnant", Valdez added.
The UK foreign office has not issued any official statement on the ongoing investigation by Lord Stevens so far.
Dodi's father, Mohamed Al Fayed, still claims the couple was murdered and is convinced that one of the reasons was Diana's pregnancy.
"I was told Diana was pregnant. Dodi told me the baby would have been my grandchild", Mohamed Al Fayed said.
