The Muslim Brotherhood's more pragmatic supporters know that an outright ban on alcohol could decimate Egypt's vital tourist trade, and further damage the already faltering economy.

They also say a defector from the underground armed movement detailed payments by Brotherhood supporters to armed factions.

The tough tactics of past elections appeared again, with the police blocking access to the polls and arresting hundreds of Brotherhood supporters.

Dr. Atef Radwan, 53, a professor at the university hospital and a Brotherhood supporter, said he spent three hours trying to vote on Wednesday.

A few minutes later, a group of angry Brotherhood supporters brought a man they said was one of the attackers to the clinic.

'Second Revolution' call Muslim Brotherhood supporters at one of the largest protests since President Mubarak was toppled.

Muslim Brotherhood supporters staged a counter-demonstration, while they were relocated from central Cairo to a location in front of Cairo University in Giza.

Four of Morsi's advisers resigned their posts in protest against the violence, which they claimed was orchestrated by the Muslim Brotherhood supporters.

His resignation was due to pressures of both the opposition and Brotherhood supporters.

This is mainly due to the rule of Sunni hardliners and Muslim Brotherhood supporters in Egypt who have opposed the Shi'ite dominated government.
