Egyptians began voting on December 15 on a constitution promoted by its Islamist backers as the way out of a prolonged political crisis and rejected by opponents as a recipe for further divisions in the Arab world's biggest nation.Queues formed outside polling stations in Cairo and other cities and soldiers joined police to secure the referendum process after deadly protests during the build-up. Egyptians are being asked to accept or reject a constitution that must be in place before a parliamentary election can be held in 2013 to replace an Islamist-led parliament that was dissolved this year. Many hope this will lead Egypt towards stability. Pope Tawadros II, head of Egypt's Coptic Orthodox church, arrived at a school in Cairo's Abbasiya and cast his ballot alongside other Egyptian voters. (Reuters video)
