In June 2009, millions of Iranians took to the streets to protest against what they considered a rigged presidential election.
The hardline incumbent Mahmoud Ahmadinejad won 62% of the vote. All three defeated candidates disputed the results.
The protests gave rise to the 'Green Movement', named after its signature colour, which opposed Ahmadinejad.
Journalist Maziar Bahari was accused of being a Western spy and spent 118 days being interrogated in Iran's Evin Prison. He tells Dan Hardoon about the torture he endured.
