Iran curbed its disputed nuclear activity under its deal with world powers.
Ahmadinejad's decision will upend an election many believed would be won by moderate President Hassan Rouhani, who negotiated the nuclear deal with world powers. It doesn't work this way, in the sense that you have many people within Iran who are shifting...
Rouhani has also lost one of his main backers: heavyweight former president Akbar Hashemi Rafsanjani, who passed away in January, played a key role in the surprising landslide victory in 2013.
The list of the applicants include Ex-President of Iran Mahmoud Ahmadinejad, former Iranian Vice-President Hamid Baghaei and several other high-ranking officials.
Last year, the country's supreme leader, Ayatollah Ali Khamenei, recommended to Ahmadinejad that he not join the field.
He previously served positions in Iran's Judiciary, as the Attorney General from 2014 to 2016, and Deputy Chief Justice from 2004 to 2014 for ten years. Registration for the election begins on Tuesday and will continue until Saturday.
Korea fires ballistic missile ahead of Trump-Xi meeting
If fired from the South's southernmost island of Jeju, the missile can reach Sinuiju, a North Korean city bordering China. A USA statement said initial assessments indicate the type of missile was a KN-15 medium-range ballistic missile.
Also on Friday Ebrahim Raisi, a hard-line cleric close to Supreme Leader Ayatollah Ali Khamenei, who had earlier announced plans to run promising to fight poverty and corruption, registered to run in the presidential elections.
However, Ahmadinejad said Wednesday that the Supreme Leader never barred him from rerunning for the presidency.
The politically moderate cleric faces a tougher than expected battle for a second term on May 19 as criticism mounts over the continued stagnation of the economy. Another favorite in the election campaign is Ebrahim Raisi, a candidate from the alliance of conservative parties, the Popular Front of Islamic Revolution Forces.
Rouhani has arrived at the Interior Ministry where candidates enroll, Trend correspondent reported April 14.
He sought to reach across political lines on Friday, saying: "I will be the candidate for the whole of Iran".
The country's Guardian Council - the highest political body in the country, which is overseen by Khamenei - then has 10 days to approve the candidates.
