Iran set to vote for next President

  

   As Iranian voters go to the polls today to vote for its next president, Hassan Rouhani is seeking a second term.

   68 year old Rouhani, a moderate cleric who negotiated a landmark nuclear deal with world powers in 2015, is standing against three other candidates.
   His main challenger is seen as 56 year old Ebrahim Raisi, a hardline cleric and former prosecutor who is close to Supreme Leader, Ayatollah Ali.
If no-one wins more than 50% of votes cast, a run-off will be held next week.
   Every incumbent president has been re-elected in Iran since 1985, when Ayatollah himself won a second term.

  More than 54 million people are eligible to vote in today's election, which will take place in 63,500 polling stations. Early election results are expected on Saturday.
