Former Nissan chairman Carlos Ghosn, speaking in Beirut after his dramatic escape from Japanese justice, said on Tuesday that the French ambassador had warned him shortly after his arrest that his own company was plotting against him.

"Frankly, I was shocked by the arrest and the first thing I asked is make sure Nissan knows so they can send me a lawyer," Ghosn told Reuters in an interview in Beirut.

"And the second day, 24 hours from this, I received a visit from the French ambassador who told me: 'Nissan is turning against you.' And this is where I realized that the whole thing was a plot."
