An Egyptian court has ordered the suspension of parliamentary elections scheduled to begin next month, throwing the country's politics into deeper confusion.
The administrative court said the law organising the elections must be reviewed by the Supreme Constitutional Court to determine its conformity to the constitution.
The ruling further complicates Egypt's political crisis over the divisions between Islamist president Mohammed Morsi and the mainly liberal and secular opposition.
The opposition had called a boycott of the elections, saying they should not be held amid anti-Morsi protests and unrest that have shaken the country for weeks.
The multi-phase election was due to begin in late April and last for nearly two months.
The government can appeal against the administrative court ruling.
