About 10,000 protesters have rallied in Casablanca against King Mohammed’s proposed constitutional changes, which they say do not go far enough.
The February 20 reform movement also rallied in other Moroccan cities. In the capital Rabat, several hundred marched in support of the reforms.
On Friday, the king proposed slightly loosening his current absolute power.
But he said he would keep total control of Morocco’s security and foreign policy, as well as matters of religion.
King Mohammed VI’s proposals will be put to a referendum on 1 July, but critics say this leaves little time for a real debate.
