Others including moderate ex-parliament speaker Ali Larijani and Vahid Haghanian, a former commander in Iran´s Revolutionary Guards, were also barred from standing.

Four women had also registered their candidacy but were disqualified, as has been the case for all presidential elections since the 1979 Islamic revolution.

Iran´s presidential elections were originally slated for 2025 but were brought forward following Raisi´s unexpected death on May 19.

Raisi and seven members of his entourage, including foreign minister Hossein Amir-Abdollahian, were killed when their aircraft came down on a fog-shrouded mountainside in northern Iran.

In Iran, ultimate authority is wielded by the supreme leader and not the president. Ayatollah Ali Khamenei, 85, has held the former post for 35 years.

Following Raisi´s death, Khamenei assigned vice president Mohammad Mokhber, 68, as caretaker president in accordance with the constitution.

In the 2021 elections, the Guardian Council disqualified multiple reformist and moderate figures ahead of the presidential elections which brought the ultraconservative Raisi to power.

Those elections had a record low turnout for a presidential poll, at just 48.8 percent.

This month´s vote will be held during a turbulent time, as the Gaza war rages between Iran´s arch-foe Israel and Tehran-backed Palestinian militant group Hamas, and amid continued diplomatic tensions over Iran´s nuclear programme
