Iranian voting fraud claims rejected
Friday’s run-off will be between the top two candidates in last week’s first round - former President Akbar Hashemi Rafsanjani and hard-line Tehran mayor Mahmoud Ahmadinejad.
Mr Rafsanjani, 70, bidding to regain the post he held from 1989 to 1997, rebranded himself as a liberal for the campaign, saying the time was right to open a new chapter in Iran-US ties and signalling he would increase social and political freedoms.
