A Swiss hospital has defended itself amid wild speculation surrounding the death of Ferrari president Sergio Marchionne.
Some have reported that the 66-year-old Italian Canadian may have died after a routine operation on his shoulder.
'One does not dies of a shoulder operation'
Il Giornale newspaper reported that there had been "sudden and unexpected complications".
"One does not die of a shoulder operation," La Repubblica added.
Actually, it is believed Marchionne - a heavy smoker - died after a battle with lung cancer, with the complications being a brain embolism or cardiac arrest.
"Due to a serious illness, Mr Marchionne was treated for more than a year. With all possibilities of cutting edge medicine exhausted, Mr Marchionne unfortunately passed away," Zurich University Hospital said in a statement.
Ferrari parent Fiat Chrysler, meanwhile, said it has "no knowledge of the facts relating to Mr Marchionne's health" beyond the shoulder surgery.
