CAIRO (AP) - Egyptian President Mohammed Morsi has called for a Dec. 15 referendum on a disputed draft constitution.

Morsi spoke Saturday in a nationally televised speech to the Islamist-led panel that hurriedly approved the draft charter amid widening opposition from secular and Christian groups.

Morsi urged Egyptians to participate in the referendum and praised the role of the judiciary in observing past elections. He says the referendum will be a brick in Egypt's democratic experience.
