Why has Morocco's king survived the Arab Spring?

Following Friday's elections, King Mohamed VI is for the first time obliged to choose the prime minister from the largest party, rather than naming whoever he pleases.

However, many of the protesters who took to the streets in February feel the reforms still fall far short of their demands for a democratic, constitutional monarchy, and have called for a boycott. A low turnout in the parliamentary poll would detract from the legitimacy of King Mohamed VI's reforms and could hint at future problems. Ahead of the poll, the sleepy calm of the capital, Rabat, was occasionally punctuated by the marches of unemployed graduates.
