Interior minister says 98 per cent of those who took part in referendum voted "yes" to King devolving some powers.
Moroccans have overwhelmingly voted to approve a revised constitution that will curb King Mohammed VI's near absolute powers in the north African nation, the country's interior minister has said.
Taib Cherkaoui, the interior minister, announced shortly after the voting closed on Friday that the poll showed 98 per cent in favour of the changes, with 94 per cent of stations reporting.
"The referendum went ahead in a normal atmosphere, and showed the degree of interaction between the people and the content of the constitutional project," he said, adding that 30 per cent of the voters were under 35.
The polls closed at 1800 GMT on Friday after 11 hours of voting and the final voting percentage was recorded at 72.65 per cent.
Mohammed announced the referendum last month in what is widely seen as a move to ward off "Arab Spring" street protests sweeping the region.
The revised constitution grants the government executive powers, but retains the king at the helm of the army, religious authorities and the judiciary and still allows him to dissolve parliament, though not unilaterally as is the case now.
It does, however, remove reference to the king as "sacred", though he retains the title of "Commander of the Faithful" and is considered "inviolable".
The new constitution will also guarantee more rights for women and will make Berber an official language, alongside Arabic.
'King has responded'
The voters who showed up at the nearly 40,000 polling stations around the country Friday tended to talk more about their faith in the king, rather than something as abstract as a new constitution.
Lachen Haddad, a member of Morocco's popular movement, told Al Jazeera that in Morocco "the king has responded to the street".
"We have democracy, now we need to have democrats to implement that," Haddad said.
"It is definitely going to be seen as a major victory for the king of Morocco, however this is not going to be the end for the pro-democracy movement. Its activists say that the referendum campaign was not balanced, it was not fair that there were targets of a smear campaign.
"This is going to be a very long, protracted political process that starts today with the reform of the constitution and then elections, which are expected in October."
On June 17, Mohammed, who took over the world's longest-serving dynasty in 1999, conceded some of his political powers to the prime minister and the parliament while keeping his role as a power broker.
"We have managed to develop a new democratic constitutional charter," he said in a televised speech, adding that the constitution "enshrines a citizenship-based monarchy".
But critics say the changes do not go far enough and a low turnout could still spur demands for bolder changes.
After the poll result was announced, Elaabadila Chbihna, a member of the February 20 movement, told the Associated Press that his group was doubtful that the result was accurate.
"Now we have become a banana monarchy,'' he said.
But while Mohammed's personal popularity may swing many voters in favour of the reforms, the margin of victory could be eroded by resentment at what is seen as a wide disparity between rich and poor, and sense of alienation from the political elite.
In Washington, Mark Toner, the US State Department spokesman, said that his country welcomed the peaceful conduct of the referendum, and saw it as "an important step in Morocco's democratic development".
