Citing three sources, Sweden's Svenska Dagbladet newspaper reported that Jean-Claude Arnault - the man reportedly at the centre of a sex abuse and financial crimes scandal that is tarnishing the academy which awards the Nobel Prize in Literature - allegedly assaulted the princess 12 years ago.
But on Saturday, the Academy's woes worsened further as details emerged about an alleged sexual harassment scandal.
Now-disgraced photographer Arnault is married to Katarina Frostenson, a poet and former member of the Swedish Academy, which picks the victor of the Nobel Prize for Literature.
Why is the Swedish Academy in crisis?
Frostenson is also accused of violating conflict-of-interest rules by failing to disclose that she was co-owner of a performance venue run by her husband, which had previously received funding from the academy.
The Swedish Royal Family's spokesperson has declined to comment on whether or not the Crown Princess was groped, and said they would neither confirm nor deny that Engdahl were given such instructions.
Last November, inspired by the #MeToo campaign, 18 women made allegations of sexual assault and harassment against him.
The organisation then voted against removing Ms Frostenson from its 18-person committee. "It has already affected the Nobel Prize quite severely and that is quite a big problem", she said at the time.
The Nobel Literature Prize has been reserved on seven occasions since it was first awarded in 1901: in 1914, 1918, 1935, 1940, 1941, 1942 and 1943. "It was all the way down", Swedish writer Ebba Witt-Brattström reportedly told The Telegraph of the incident.
With just ten active members, rumors are circulating that the Academy may cancel the 2018 Nobel Prize in Literature. A decision is expected on may 3. The views expressed therein are not necessarily those of stlucianewsonline.com, its sponsors or advertisers.
