A weekend referendum on a draft constitution called by President Mohamed Morsy is dividing Egypt, with many people swayed by their support or animosity for Morsy's Muslim Brotherhood.

Hamdi Imam, a Cairo bookseller, is a picture of composure far from the anger that has rocked Egypt in the past three weeks.

But the 50-year-old, sitting on the pavement off a busy main road concentrating on his crossword puzzle, is anything but oblivious of the mess the country is in.

"The constitution has blood on it, it's wrong," he says.

"It shackles people. From the beginning it was clear the Muslim Brotherhood shouldn't run a country. They will destroy Egypt."

"The Brotherhood is not a party of religion, they are of infidel politics."

It is 28-year-old Mohammed Hassan, dressed in Western clothing, who is the first to voice support for the Islamists.

"The Brotherhood are good," he says.

"No one's given them a chance, they've only been in power for five months. (Former dictator) Hosni Mubarak was there for 30 years. People have been saying they're bad for so long that everyone automatically thinks so."AFP
