Egyptians are preparing to vote on the draft constitution backed by President Mohammed Morsi's Muslim Brotherhood.

The referendum will take place on Saturday, but has been rejected by the opposition.

It has led to violent clashes and the biggest crisis since President Hosni Mubarak was toppled nearly two years ago.

The BBC's chief international correspondent Lyse Doucet reports from President Morsi's hometown of Zagazig.
