With no signs of Carlos Ghosn's five-month legal drama wrapping up anytime soon, his wife has assumed a starring role in the former Nissan Motor Co. chairman's defense, becoming his chief spokeswoman and crisscrossing the world to appeal to both the public and politicians on his behalf.

Carole Ghosn has flown to France to ask the government there to intervene in the case, returned to Japan for questioning by prosecutors and appeared in multiple media interviews in the United States where she has repeatedly proclaimed her husband's innocence. She even penned an op-ed asking U.S. President Donald Trump to act.

But while the media blitz may generate some sympathy, it's not likely to have a significant impact on the outcome of the case, experts interviewed by The Japan Times said Friday.
