Hundreds of supporters of the Egyptian President have forced a court to postpone a hearing on the country's new constitution. 

The protesters, many of them members of Mohammed Morsi's Muslim Brotherhood, are trying to prevent judges from examining the Islamist-dominated parliament - and the body behind the draft constitution. 

The case threatens to deepen the political crisis in Egypt - which was sparked by a decree granting President Morsi new powers. 

Opponents say the country's democratic reforms have been stalled by Morsi.
