A delay in parliamentary elections in Egypt looks inevitable after the Supreme Court struck down a part of an election law after deeming it unconstitutional, a report said.
The law pertained to the definition of electoral districts, reported the BBC.
Voting was due to start on March 21 and run into April. However, an electoral commission spokesman said that a "new timetable" was now being drawn up in the wake of the recent ruling.
Egypt's main assembly was dissolved in 2012 and the election is widely expected to be the final transition from military rule.
Former army chief Abdul Fattah al-Sisi assumed power after ousting Muslim Brotherhood President Mohammed Morsi in 2013. He was elected President in May 2014.
Sisi approved a constituency law in December, creating 567 parliamentary seats. Of these, 420 seats would be contested by individual candidates while 120 would be allocated to party lists and 27 assigned by the president.
However, following the court ruling, Sisi has asked for the law to be redrafted within a month. Candidates will then be asked to re-register themselves.
