That's what Spain's El Imparcial is saying (translation). According to the paper, Mohammed has been staying in France for more than 30 days, and everyone from Moulay Rachid to Nicholas Sarkozy are begging him to go home.
The article goes on to say that the king's absence has caused a shutdown in the government because he is too busy in France to exercise his absolute authority over the country. He's skipping conferences that he's invited to, like the Tokyo Conference on African Development. Moroccan elites are apparently so afraid that they're sending their families out of the country until things calm down.
If it's true, it's a great opening for Sahrawis, both in Polisario and under occupation.
