Multiple theories related to the death of Princess Diana have emerged over the period of time. At the same time, several theories about the Princess' relationship with Prince Charles are also swirling around. However, a new play makes some controversial claims.

Mirror UK is reporting that the West End play "Truth, Lies, Diana" claims that Princess Diana was pregnant with a baby on the night she died. The play that opened in London recently suggests that the Princess was carrying her lover Dodi Fayed's child, who also lost his life alongside Diana on Aug 31, 1997. The duo reportedly was travelling in a car that met with an accident in Paris.

As per the report, the play revolves around the fictional investigation of Princess Diana's death in 1997 by a journalist called Ray. The character is reportedly trying to determine what actually happened. The man behind the play is writer and director Jon Conway.

Despite pregnancy claims being dismissed in the transcripts from the inquest, the several allegations displayed in the play also include the "testimony" Jon Conway claims to have received from a British forensic officer Rose. Rose happens to be the ex-girlfriend of a doctor at the hospital where Princess Diana was declared dead.

In the play, the scene shows Rose claiming that doctor Yasser called another doctor. "Yasser said to him in Arabic, 'I can't believe the news. Were you on duty?' Then he said, 'Yes, yes... What? She was pregnant?'" Rose says in the play. Furthermore, the doctor is seen telling Yasser that "he saw the foetus and was told never to mention it."

The play addresses the question why the duo kept quiet at the time Princess of Wales' death was announced. In the play, Rose says they wanted to protect their careers. However, now she feels "it's time for the truth to come out."

The play brought to the stage several unproven allegations from life of Princes Diana. Some includes those alleged by Princess' former flame James Hewitt. It was said that the deceased royal discovered Prince Charles and Camilla parker Bowles' secret affair just few days before her wedding to the Prince. At the time, she reportedly wanted to cancel the wedding. Furthermore, it is shown that Prince Charles knew about Princess Diana's affair and he apparently "encouraged it so that he could be with Camilla."

The report notes Jon Conway carried out "extensive interviews with experts" and people who were close to Princess Diana including James Hewitt and butler Paul Burrell. Besides, the play also posed allegations of having "many extra-marital flings" on Prince Philip. It is heard in the play that the king and the queen "had an arrangement."

"James [Hewitt] told me some quite remarkable things that have never been said in the public domain, particularly about when his relationship with Diana started," Conway said. The report notes that many Royal commentators have objurgated the play and the content it shows.

Margaret Holder, writer and documentary maker says that Jon Conway is maybe trying to put himself "back in the spotlight." Royal biographer Hugo Vickers said: "If you talk to certain people you will get a version of events these people are keen to peddle. They have an agenda of their own."

Meanwhile, Jon Conway seems to be okay about the criticism the controversial play brings along with it. "I think it's important the public is able to hear the whole story. I call it the D-word as nobody wants to talk about it," he said.
