At least 24 people were killed and several others injured during the month-long demonstrations following the elections. Hundreds of demonstrators have been jailed in the subsequent violent crackdown by Iranian security forces.

Meanwhile, Iran's Guardian Council, the most influential body currently dominated by conservatives, has published a 'detailed report' on the country's disputed presidential election, showing how complaints about the results were dealt with.

Earlier in July, the council's Spokesman Abbas-Ali Kadkhodei had announced that the report would be published to resolve any ambiguities that some people may say were surrounding the election process.

In order to 'thwart the plots' and to 'promote unity' the report on the election is published for the first time, the council said in a preface, which confirmed that the results were authentic, Press TV reported.

Many believe that Rafsanjani's long-awaited sermon could pour water on the ongoing fire of protests or add more fuel to the dispute in the wake of the election results confirmed by the Guardian Council.
