Tens of thousands of people have gathered in central Cairo for a seventh day of protest, calling for a general strike. Police have been ordered back to the streets, to positions they abandoned on Friday, but it is not clear whether they are returning to central Cairo. The demonstrators are also planning a huge march to take place on Tuesday. Protesters want President Hosni Mubarak to step down after 30 years in power. He has promised political reform. The president has ordered his new Prime Minister, Ahmed Shafiq, to push through democratic reforms and create new jobs. Correspondents say all the signs continue to suggest that the only change the protesters will settle for is Mr Mubarak's removal from office. Meanwhile, Moodys Investor Services has downgraded Egypt's bond rating and changed its outlook from stable to negative, following a similar move by Fitch Ratings last week. Both cited the political crisis. 'Protest of millions' But there were signs of disagreement within the opposition, with the largest group, the Muslim Brotherhood, appearing to go back on its endorsement of leading figure Mohamed ElBaradei as a negotiator with Mr Mubarak. As demonstrations enter their seventh day, correspondents say there are at least 50,000 people on Tahrir Square in the centre of the city. The BBC's Jim Muir in Cairo says the military, who have cordoned off the square with tanks, are very relaxed and letting people come and go. Elsewhere the streets are busy and things appear to be returning to normal, with some police returning and seen directing traffic. But there are no riot police, and our correspondent says the government is being quite clever in keeping the unpopular police force out of contact with the protesters. There are plans for a "protest of the millions" march on Tuesday. Our correspondent says this is an attempt to reinvigorate the movement, as many are wondering what to do next if Mr Mubarak stays in power, as he is showing every sign of doing. On Sunday, most of the crowd in Cairo's Tahrir (Liberation) Square were unfazed by low-flying air force jets and a helicopter. "Change is coming," promised Mr ElBaradei when he addressed the crowds. Mr ElBaradei has been mandated by opposition groups to negotiate with the regime. But a spokesman for the largest opposition group, the Muslim Brotherhood, appeared to reject this position. "The people have not appointed Mohamed ElBaradei to become a spokesman of them," Mohamed Morsy told the BBC. "The Muslim Brotherhood is much stronger than Mohamed ElBaradei as a person. And we do not agree on he himself to become representing [sic] this movement, the movement is represented by itself, and it will come up with a committee... to make delegations with any government." Thousands have rallied in Alexandria, and there have also been sizeable demonstrations in Mansoura, Damanhour and Suez. Economic impact The unrest is having an impact on the Egyptian economy, beyond the closure of shops and businesses and the call for a general strike. The US, Japan and China are among states preparing to evacuate their citizens. Tourism is a vital sector in the Egyptian economy, accounting for about 5-6% of GDP. International pressure is growing for some kind of resolution. In the strongest language yet, both US President Barack Obama and his Secretary of State Hillary Clinton talked about the need for an "orderly transition" to a democratic future for Egypt. The White House says Mr Obama made a number of calls about the situation over the weekend to foreign leaders including Turkish Prime Minister Recep Tayyip Erdogan, King Abdullah of Saudi Arabia and British Prime Minister David Cameron. The protests in Egypt are top of the agenda of a meeting of European Union foreign ministers in Brussels on Monday. The unrest in Egypt follows the uprising in Tunisia which ousted President Zine al-Abidine Ben Ali two weeks ago after 23 years in power. Source: BBC
