Dueling mass demonstrations are scheduled in Egypt Sunday both in support and in opposition to President Mohamed Morsi and his Muslim Brotherhood ruling party, with opposition activists calling the protests “a second revolution,” The Guardian newspaper reported Friday.

“It’s a second revolution,” the Guardian quoted Ahmed Said, a leader of the National Salvation Front (NSF), the secular opposition’s largest coalition, as saying. “The semi-final was played on 25 January 2011. This is the final. I don’t know how long it will take, but Morsi’s going to go – and Egypt will never be the same after the 30th.”

Opposition activists say they have collected 15 million signatures to a petition demanding Morsi’s removal, and expect a significant proportion of that number to take to the streets on 30 June.

Islamists have already turned out in force, with at least 100,000 having gathered in Cairo last Friday to support  Morsi – and plan to do so again this week.

Smaller protests around the country Thursday left one person dead and 30 injured as supporters and critics of Egyptian President Mohamed Morsi took to the streets, the health ministry reported.

Fighting took place in the northern Nile Delta province of Sharqiya, said the ministry, cited by the official MENA news agency.
