The Muslim Brotherhood's Mohammed Mursi has been declared the winner of Egypt's presidential election run-off.


He won 51.73% of the vote, beating former PM Ahmed Shafiq, the Higher Presidential Election Commission said, according to BBC News.


The head of the panel of judges, Farouq Sultan, said it had upheld some of the 466 complaints by the candidates, but that the election result still stood.


The announcement prompted scenes of jubilation in Cairo's Tahrir Square, where Mursi's supporters gathered.


They have been maintaining a vigil there in protest at the series of decrees and appointments by the ruling Supreme Council of the Armed Forces (Scaf) designed to reduce or constrain the power of the president, and entrench the power of the military.


On 13 June, the military-controlled government gave soldiers the right to arrest civilians for trial in military courts until the ratification of a new constitution.


Four days later, just as the polls were closing in the presidential run-off, the generals issued an interim constitutional declaration that granted them all legislative powers and reinforced their role in the drafting of a permanent constitution. The document also exempted the military from civilian oversight.


Then on Monday, the head of the Scaf, Field Marshal Mohammed Hussein Tantawi, announced the re-establishment of a National Defence Council, putting the generals in charge of Egypt's national security policy.
