The daughters of Nissan Motor Co.'s former chairman Carlos Ghosn, indicted on suspicion of violating Japan's financial reporting laws, believe the accusations are part of an internal revolt within the carmaker to prevent a merger with Renault, the New York Times reports.

His eldest daughter, Caroline Ghosn, said when she saw Nissan Chief Executive Officer Hiroto Saikawa's televised news conference and heard him condemn her father, she suspected that the company investigation had been started over opposition to a tie up between Nissan and Renault that her father was trying to arrange.

"For Saikawa to so adamantly denounce someone who had been his mentor and then immediately without any benefit of the doubt condemns him," said the 31-year-old, in the first interview since her father's Nov. 19 arrest. "He didn't even waste a breath. He didn't even try to cover up the fact that the merger had something to do with this," she added.
