Update: Ros in Portland and Lyse Doucet in Tehran co-presenting the programme
Is something changing in Iran ?
Since a series of TV debates, the election campaign has burst into life.
Our BBC correspondents in Tehran say the outcome will be close, but it’s just possible that hardline President Ahmedinijad could be defeated by a “reformer” Mir Hossein Mousavi (pictured with his wife Zara Rahnavard).
There have been football-style demonstrations on the streets for both main candidates and one of our team there – Jon Leyne – says Iran has been changed for ever.
Interpretations vary, but a defeat for the incumbent could lead to a softening of the country’s stance against the USA, Israel and the nuclear programme. Maybe.
We’ve asked our election team in the Iranian capital to ask some voters there to talk to our audience in Portland, Oregon – and you.
