Auburn Hills, Michigan - Fiat Chrysler said on Thursday that it "had no knowledge of the facts" related to the health of boss Sergio Marchionne, who died this week, after the hospital that treated him announced he had been seriously ill for more than a year.
The Italian auto giant scrambled for a succession plan late last week after reports that Marchionne, 66, was gravely ill after suffering serious complications following surgery on his right shoulder last month.
The hospital that treated Marchionne, who died on Wednesday, broke its silence on Thursday.
"Patients' confidence in receiving the best possible treatment and discretion are of utmost importance," the University Hospital Zurich (USZ) said in a statement.
However, the hospital "is being confronted with various rumours in the media about his medical treatment".
