Benflis formed his own party in 2015, Talaie El Houriat, Arabic for Vanguard of Freedoms. The 82-year-old Bouteflika, who has yet to say whether he will seek a fifth term, has announced the election for April 18.
Benflis became the second official candidate after Ret. Gen. Ali Ghediri said Saturday he would run for president. Other potential candidates have until March 4 to register with the constitutional court.
