The EU says "it is a major step which highlights a clear commitment to democracy and the respect for human rights."
"We praise the announcement made by the King of Morocco of the main provisions of the new constitution, which will be put to a referendum on 1 July 2011," said EU foreign policy chief, Catherine Ashton, and EU Enlargement Commissioner, Stefan Fule.
"The proposed amendments concern key elements of the reform and modernisation, such as the separation of powers, the strengthening of the government's role, the independence of the judiciary, the regionalisation and gender equality," they added.
"Once the new constitution is implemented, it will be a major achievement in the process of reforms that was already undertaken in Morocco," they noted, expressing the readiness of the EU to "support Morocco's efforts to implement these profound reforms."
"The project of constitutional reform conforms to the ambitions of the Advanced Status granted by the European Union to Morocco," they said.
