Rafsanjani's return?

The FT reported on Saturday that Akbar Hashemi Rafsanjani may stand in Iran's presidential election in June. He is said to be concerned about the rise of the power of 'hardline' conservatives. What seems to have happened is that the rigging of last year's parliamentary elections - to exclude the Khatami-like 'reformists' - went too far and the 'pragmatic' conservatives lost control to the hardliners.
