A look at the six candidates in Iran's presidential election Friday. Two others -- parliament member Gholam Ali Haddad Adel and former Vice President Mohammad Reza Aref -- withdrew earlier this week.
SAEED JALILI: Iran's top nuclear negotiator since 2007 and considered a hardliner. Jalili, 47, is believed to have backing from many in the ruling theocracy, including possibly Supreme Leader Ayatollah Ali Khamenei. He also gained the support of ultraconservative cleric Ayatollah Mohammad Taghi Mesbah Yazdi, who was previously seen as the spiritual mentor of outgoing President Mahmoud Ahmadinejad.
At campaign stops, Jalili's slogan was chanted by supporters: No compromise; no submission. Jalili also is often hailed as a "living martyr" because of losing part of his right leg in 1980-88 war with Iraq.
He worked as a university lecturer before joining the Foreign Ministry in 1989, where he rose in the ranks until his appointment in 2001 as a senior policy adviser in Khamenei's office. He later served as an adviser to Ahmadinejad and deputy foreign minister for European and American Affairs. He took over the important nuclear negotiator role in 2007 -- in a move that surprised even some Iranian hard-liners for his rapid rise.
A U.S. diplomatic cable at the time -- part of the documents made public by WikiLeaks -- interpreted the decision as "a move to forestall any compromises on the nuclear issue." Another cable in January 2008 noted that a European Union official described Jalili as unbending, dogmatic and "a true product of the Iranian Revolution."
HASAN ROWHANI: A former nuclear negotiator and close ally of former President Akbar Hashemi Rafsanjani, who was blocked from the ballot by Iran's election overseers. Rowhani, 64, is the only cleric among the candidates and viewed as a relative moderate. He has drawn support from reformist leaders after a rival, former Vice President Mohammad Reza Aref, dropped out of the race in attempts to consolidate the liberal-leaning camp.
Rowhani started religious studies at a teenager and soon established himself as an outspoken opponent of the Western-backed shah, traveling frequently for anti-monarchy speeches and sermons that caught the attention of Ayatollah Ruhollah Khomeini, the eventual leader of the 1979 Islamic Revolution.
Rowhani graduated from Tehran University with a law degree in 1972. He then says he went abroad to Glasgow Caledonian University for a master's degree in legal affairs. After the revolution, Rowhani rose quickly with various roles, including reorganizing the military, serving in the new parliament and overseeing the state broadcaster. He strengthened his ties to Rafsanjani during the 1980-88 war with Iraq and, later, as Rafsanjani's top national security adviser during his 1989-97 terms.
Rowhani took over the nuclear portfolio in 2003, a year after Iran's 20-year-old nuclear program was revealed. Iran later temporarily suspended all uranium enrichment-related activities to avoid possible sanctions from the U.N. Security Council.
Ahmadinejad strongly opposed any such concessions. Rowhani resigned as nuclear negotiator and head of the Supreme National Security Council after a few testy postelection meetings with Ahmadinejad.
At campaign rallies, Rowhani has pledged to seek "constructive interaction with the world" that includes efforts to ease Western concerns about Iran's program and lift punishing international sanctions that have pummeled the economy.
MOHAMMAD BAGHER QALIBAF: Tehran mayor and former commander of the Revolutionary Guard during the Iran-Iraq war.
Qalibaf, 51, has built a reputation as a dynamic leader for a host of quality-of-life projects around Iran's capital including parks, expanded subways lines and highways. But he also has faced accusations that he took part in crackdowns against student protesters in 1999 while with the Guard and, four years later, allegedly ordered a full-scale assault to crush another flare-up of student unrest.
Like many Iranian leaders of his generation, Qalibaf got his footholds in power during the 1980-88 war with Iraq.
Qalibaf was a Revolutionary Guard commander and later appointed to run one of the Guard's main economic conglomerates. He was appointed as the Guard's air force commander in 1997 despite not being a flier, but later received his license and now sometimes pilots passenger planes.
He was named head of Iran's police forces in the shakeup after the 1999 Tehran University riots, which marked one of the first major displays of dissent against Iran's ruling clerics.
Qalibaf also brings a rare element in Iran's macho politics: A high-profile wife who has carved out her own political identity.
Zahra Sadat Moshiri, a former professor of social sciences at Tehran's Sharif University of Technology, has served as Qalibaf's adviser on women's affairs for Tehran. She has hosted many conferences on women's issues, including some that reflect her views about balancing Islamic traditions with needs to advance women's roles on all levels including politics.
