Egyptian Opposition Calls For Protests After Referendum on Draft Constitution

Islamist-backed document received 57 percent of "yes" votes in a vote that some are saying was fraudulent

(Reuters) - Egypt's opposition called for nationwide protests against a constitution backed by President Mohamed Mursi, after a vote exposed deep divisions that could undermine his efforts to build consensus for tough economic measures.

The Islamist leader won a 57 percent "yes" vote for the constitution in a first round of a referendum at the weekend, according to state media, a margin that was less than his party had hoped for and which is likely to embolden the opposition.
