The SCAF also said that the results of the elections proved their neutral standing for all candidates, adding that they respected people's will.

Egypt's Prime Minister Kamal el-Ganzouri and Morsi's defeated rival Shafiq also congratulated him on his victory.

Meanwhile, the Egyptian Coptic Church and the Al-Azhar Mosque also delivered their congratulation to Morsi.

Earlier this day, after hearing the news of Morsi's victory, members of his campaign stood silent for one minute to mourn the death during last year's turmoil.

"We thank all the Egyptians, to them we are grateful to win the presidency and also our thanks are extended to Egyptian army, judiciary and police," said Ahmed Abdel Aaty, a senior campaigner of Morsi.

The membership for Morsi in the Muslim Brotherhood movement has ended, to affirm the pledge for the movement that Morsi will be the president for all Egyptians.

Spokesman for Morsi's campaign Yasser Ali told reporters that Morsi will be sworn in by the parliament, which was dissolved by the Supreme Constitutional Court on June 14.

Tens of thousands of Morsi's supporters celebrated and fired fireworks in the Tahrir Square in downtown Cairo after learning Morsi's win.

Mohsen Mohamed, a 34-year-old from the April 6 Movement, expressed happiness for Morsi as the country's new president. "If Shafiq won the presidency, so the results would have been forged," Mohsen Mohamed told Xinhua at Tahrir Square, the epicenter of last year's turmoil which led to the fall of former leader Hosni Mubarak.

"I wasn't a supporter of Morsi, but anyway Morsi is better than Shafiq who is a symbol of Mubarak's era," said Mohsen Mohamed.

"We will continue in our sit-in in Tahrir, until the supplementary constitutional declaration is cancelled," he said.
