Egypt's new constitution has been passed with 63.8 per cent voter support after two rounds of nationwide referendum on December 15 and 22.

The electoral commission of the country announced that voters had approved overwhelmingly the constitution drafted by President Mohamed Mursi's Islamist allies.

It gave Islamists their third straight victory at the polls since Hosni Mubarak was toppled in a 2011 revolution.

Our West Asia Correspondent reports that this is the first constitution since Mubarak's ouster.He adds that the results of the constitutional referendum were along expected lines and the Islamist parties have hailed it as yet another step towards democracy and stability in Egypt.

However the liberal secular opposition led by National Salvation Front has alleged large scale poll violations and vowed to fight for the rights of Egyptian people.

The constitutional referendum will be followed by fresh elections for the lower house of the parliament or the National Assembly within two months.

In the interim period, the law making authority will be vested with the upper house of the parliament or the Shura Council. The council otherwise is an advisory body.

It has 270 members out of which 180 have been elected in the polls held earlier this year while 90 other members were appointed two days ago by President Mursi well within his powers. The Egyptian President has already convened the meeting of the Shura Council today.
