PARIS, Feb 6 (Reuters) - French investment firm Eurazeo (EURA.PA) ousted Chief Executive Virginie Morgon on Monday and named a new executive board following a row with the group's number one shareholder, the Decaux family, a source close to the matter said. Jean-Charles Decaux, Eurazeo's chairman, pushed for the decision after a number of matters caused friction between Morgon and the Decaux family, which owns 18% of Eurazeo, the source said. A spokesperson for Jean-Charles Decaux, who is also co-CEO of JCDecaux (JCDX.PA), the world's biggest outdoor advertising firm, declined to comment. In a statement Jean-Charles Decaux, Eurazeo's supervisory board president, called the newly appointed executive board "collegial" and "focused".
