Renault SA RENA.PA and Nissan Motor Co 7201.T have entered discussions to reorganize their capital alliance structure in a bid to water down Paris's control of the French automaker, the Nikkei business daily reported on Wednesday. The paper said a plan being floated was for Renault to lower its stake in Nissan below 40 percent from the current 43.4 percent - a move that would, under French law, allow the Japanese partner's stake in Renault to carry voting rights.
