he's independent since the beginning.
anyway Murr played a clever game, in 2005 when he was hated from all the Lebanese people he benefited from the need of FPM to make new alliances because the other parties of 14 March 2005 betrayed us and made the "fourfold alliance" (ta7elouf roube3e) so he allied himself to FPM in order to guarantee his parliamentary seat..
nowadays when he saw that the Lebanese people forgot his old positions he came back to announce his independence, maybe he found that his son Elias Murr Rambo will lose the ministry chair, so micho wants to guarantee it again in the next government.
anyway no problem, in August 07 everyone knows that Murr gave his votes to Amin Gemayel but FPM won in the end. we'll see if he'll leave the FPM-Tashnag alliance in 2009 elections, anyway if he done it i don't think Tashnag will do it
