Airbus Group (AIR.PA) said it is selling a further 15 percent stake in business and fighter jet maker Dassault Aviation (AVMD.PA) as it continues to unwind its 16-year-old link to its defense market rival. The move will see Airbus’ stake drop to around 27 percent from 42 percent, it said in a statement on Wednesday. Dassault Aviation, which has asked Euronext to suspend trading in its shares, said it will take part in the placement by purchasing a maximum of 5 percent of its share capital at a maximum price of 980 euros a share.
