MILAN/DETROIT (Reuters) - Fiat Chrysler Chief Executive Sergio Marchionne has canceled his appearance at the Paris auto show, a spokesperson for the carmaker said on Tuesday without giving any details.

Marchionne, who also serves as CEO and chairman of luxury sportscar brand Ferrari <RACE.MI> <RACE.N>, was meant to meet with journalists on Thursday.

"The media availability with Sergio Marchionne on Sept. 29 at the Paris Motor Show has been canceled," FCA <FCHA.MI> <FCAU.N> said in a statement. A spokesperson later added that Marchionne would not be coming to the show at all.

A year ago, Marchionne canceled his appearance at the Frankfurt auto show after FCA was picked as the target company in labor talks in the United States.
