"Bribery" and "quid pro quo" are certainly the buzzwords of the fall, as first the President, and now Fiat Chrysler, have found out the hard way.

In the latest stunning twist gripping the troubled auto sector, moments ago General Motors filed a federal racketeering lawsuit against Fiat Chrysler and its former executives including its now deceased former CEO, the late Sergio Marchionne,according to CNBC. The suit alleges that the Italian automaker bribed UAW officials to receive more favorable terms during its labor negotiations. 

GM said it will seek "substantial damages" from FCA, but did not specify an amount.

GM's general counsel Craig Glidden commented: "This lawsuit is intended to hold FCA accountable for the harm its actions have caused our company and to ensure a level playing field going forward."
