Egyptian voters have approved a new Constitution by 98.1 percent, the elections chief said on Saturday, in what the government declared a popular endorsement of the army's overthrow of Islamist president Mohammed Morsi.

The result of the Tuesday-Wednesday vote had never been in doubt, as Morsi's Muslim Brotherhood and other Islamists boycotted it, but the authorities wanted a large turnout in the first democratic test since the ouster in July.

Army chief Abdel Fattah al-Sisi, the general who led the overthrow, had been monitoring the outcome for an indication of support for a possible presidential bid, military officials said.

Electoral commission head Nabil Salib said turnout "reached 38.6 percent" of 53 million registered voters, with only 1.9 percent voting "no."

That turnout proved "that the revolution of June 30 was a popular revolution," a senior government official said at a news conference to announce the results.

It "refuted the doubts of naysayers," said Salah el-Din Abdel Sadeq, head of the government's media arm.

The new charter replaces an Islamist-inspired one adopted in a December 2012 referendum under Morsi with about two-thirds of the vote and a 33 percent turnout.

The United States, a major source of financial aid that is mostly military funding, reacted to the news by urging Egyptian authorities to fully implement the rights guaranteed under the Constitution.

"It's not one vote that determines a democracy. It's what comes next that will shape Egypt's political, economic and social framework for generations," said US Secretary of State John Kerry.

"As Egypt's transition proceeds, the United States urges the interim Egyptian government to fully implement those rights and freedoms that are guaranteed in the new Constitution for the benefit of the Egyptian people, and to take steps towards reconciliation," he said.

The US administration on Thursday said it was closely watching the results of Egypt's referendum, but had not yet decided whether to unfreeze some $1.5 billion in aid.

The military removed Morsi days after millions of protesters began rallying against him on June 30, setting off months of unrest by his followers who decried what they called a "coup."

Presidential and parliamentary elections have been promised for later this year.

Sisi is wildly popular among the millions who took to the streets against Morsi, but the Islamist's followers revile the military leader for what they say was a "coup" against Egypt's first freely elected and civilian president.

The now-banned Brotherhood, harried by a deadly crackdown since Morsi's removal, dismissed the referendum as a "farce".

The group has called rallies for Jan 25, the third anniversary of the 2011 uprising that overthrew veteran strongman Hosni Mubarak.

Interior minister Mohamed Ibrahim also called for demonstrations the same day to counter an Islamist "plot to spark chaos", an unusual appeal from the top official tasked with enforcing a law that restricts protests.

More than 1,000 people, mostly Islamists, have been killed and thousands imprisoned in a police crackdown on pro-Morsi protests.
