Chairman of the panel of 50 that amended Egypt's constitution Amr Moussa denounced calls to delay the parliamentary elections.
Moussa described such calls as a setback that could hinder democratic progress.
He added that postponing the parliamentary elections was a direct contradiction to the constitution.
"The 2014 constitution was the result of unprecedented unanimous consensus," he said, adding that some people were trying to undermine it to reach compromises or political dividends.
