Morocco is the latest nation to be affected by political unrest sweeping north Africa.
Thousands of people have marched in Moroccan cities to demand that King Mohammed VI give up some of his powers.
Protestors have been out in the streets of the capital of Rabat and Casablanca while another was planned for Marrakech.
Protests have spread across the region into Bahrain and Libya since popular movements in Tunisia and Egypt forced out leaders.
Morocco, unlike other countries that have seen protests, has a successful economy, an elected parliament and a reformist monarchy, making it less vulnerable to a major uprising than other countries.
The latest development came as British travellers were warned against all but essential travel to Libya amid reports that at least 200 people have been killed in a crackdown on demonstrators in the country’s second city Benghazi.
The Foreign and Commonwealth Office said: “In light of ongoing demonstrations we advise against all but essential travel to Libya.
“We will continue to monitor the situation in Libya and reflect this in our travel advice.
“All those British Nationals without a pressing need to remain in the country should leave by commercial means if it is safe to do so.
“The British Embassy in Libya is in contact with the British community through our consular warden network and is providing consular assistance and advice.”
