Carlos Ghosn, the ousted chairman of Nissan Motor Co. who escaped from Japanese authorities last week, held a press conference Tuesday in Lebanon in which he lashed out at several Nissan executives, including former chief legal officer Hari Nada, as well as the Latham & Watkins law firm.

Nissan reassigned Nada last October after Nada became a whistleblower and key witness against Ghosn. The company said Nada would remain a senior vice president and become a senior adviser on legal action.

Nissan hired Latham & Watkins to conduct an internal investigation into Ghosn's alleged misconduct.

Declaring his innocence, Ghosn spoke of "collusion" and conflicts of interest among Japanese prosecutors, Latham & Watkins and Nissan executives, including Nada.

"The collusion between Nissan and prosecutor is everywhere," he said. "Witnesses who were in Nissan told me about all the visits that took place before my arrest."

Latham & Watkins did not immediately return calls seeking comment. Nada could not be reached.

In an earlier statement, Nissan called Ghosn's fleeing "extremely regrettable" and defended removing him from office for the financial misconduct "charged by Japan's legal authorities."

Ghosn claimed his arrest over a year ago on charges of financial misconduct was due to a "plot" against him. He said, "I have come to learn that my unimaginable ordeal over the last 14 months is the result of the handful of unscrupulous, vindictive individuals at Nissan."

He said some of his "Japanese friends thought the only way to get rid of the influence of Renault on Nissan is to get rid of me." Ghosn speculated that financial troubles at Nissan that started in early 2017 prompted them to act against him.

He accused Nissan of spending $200 million on an internal investigation to determine if he misappropriated $15 million from the company, while damaging the automaker's reputation and causing the stock price to drop.

In his hourlong press conference and two hours of media question and answers afterward, Ghosn explained that he fled Japan because he did not think he could get a fair trial. He offered to stand trial in one of three other countries where he holds citizenship: the U.S., Lebanon or France.

Since his escape, Ghosn reportedly has been in contact with Paul, Weiss, Rifkind, Wharton & Garrison, one of the international law firms representing him. Paul Weiss chairman Brad Karp declined comment Tuesday, citing attorney-client privilege.
