Its because she was pregnant by the Dodie fellow and the future King William would have had a Muslim half brother which would never do as the King is head of the Church of England. She would also have converted to Islam and its possible she would have blown herself up in the presence of Her Majesty the Queen so all round its a good thing that accident just happened to happen when it did.
The Muslim angle & being pregnant are the most likely reasons.
