Judge Abdel-Aziz Salman was appointed on Tuesday as new secretary general to the Presidential Electoral Commission (PEC), in accordance with the orders of the commission head, Judge Anwar El-Assi.

Salman, senior head of the commissioners' authority at the Supreme Constitutional Court (SCC), is to succeed Hemdan Fahmy.

PEC is the judicial body overseeing the upcoming presidential polls.

Fahmy, who has been holding the post of PEC's secretary general since December 2013, has been appointed as deputy head of the SCC.

The decision came during the SCC's general assembly held on Tuesday.

Judges Tarek Shebl and Tarek Abdel-Eleim, two other heads of the commissioners at SCC, have been designated to the PEC's general secretariat.

Egypt's second post-revolution presidential elections are due to take place on 26 and 27 May, with the coming president expected to be elected by 26 June at the latest, according to PEC.

Until this moment, the only candidates to have declared their intentions to run are Hamdeen Sabahi, who finished third in the 2012 elections, and former defense minister Abdel-Fattah El-Sisi, whose popularity soared following the ouster of Islamist president Mohamed Morsi last July.

The presidential race will be followed by parliamentary polls which, according to the 2014 constitution, must start within six months of the ratification of the national charter.

The post-Morsi constitution was approved by an overwhelming majority on 18 January.
