The judicial committee overseeing the referendum on Egypt's new constitution is yet to decide a date to announce the final results of the vote, a member said on Monday.

Mohamed al-Tanboly added in a phone call to a news agency on Monday that the committee will only announce the referendum's results after it is finished hearing all the challenges filed against it.

The committee will not take into account any results produced by any other source, the committee member insisted.

The first round of a referendum on a new constitution written by an Islamist-led assembly took place on December 15 while the second round took place on December 22.

Preliminary results show that at least 60 percent of Egyptians approve of the controversial charter that is widely discredited by opposition forces.
