Carlos Ghosn officially ousted from Nissan, still locked in detention cell

Carlos Ghosn has been officially ousted from Nissan, with the Japanese company's board voting to remove the former automotive heavyweight from his roles as chairman and representative director. Greg Kelly, also named in the allegations levelled at Ghosn, was also removed as representative director.

In making its decision, the Nissan board - which voted unanimously after a last-minute bid by Renault to delay the decision - released a statement reading: "The board acknowledged the significance of the matter and confirmed that the long-standing alliance partnership with Renault remains unchanged and that the mission is to minimise the potential impact and confusion on the day-to-day cooperation."

Fellow alliance member Mitsubishi Motors is expected to stand Ghosn down as chairman next week, while Renault has opted to name an interim replacement while the investigation into Ghosn plays out.

It completes a stunning fall from grace for Ghosn, with reports out of Japan describing the Tokyo detention centre he's currently being housed in as an infamously "austere" and "cold" facility where inmates are kept in solitude and baths are allowed just twice a week.

And they're conditions he might have to get used to, with Ghosn facing a maximum penalty of 10 years in prison and a fine of up to 10 million yen ($123,000) if he is found guilty of allegedly underreporting his salary by around five billion yen ($61m) over a five-year period from 2010 to 2015. He also faces allegations of using company assets for personal use.

Reports out of Japan also claim Ghosn was given homes across the world by Nissan, with properties in Amsterdam, Paris, Beirut and Rio de Janeiro, for which he was only asked to pay a portion of the rent, despite the actual bills running to millions of dollars.

The latest unconfirmed leak suggests Nissan had paid Ghosn's sister some $138,000 a year for the past 16 years for an advisory role that didn't exist, as well as providing her with an apartment in Rio de Janeiro that was paid for by a Nissan subsidiary.
