Protestors are expected to gather again outside the Iranian embassy in London this evening as the political crisis in Iran continues.
Presidential candidate Mir Hossein Mousavi was defeated in presidential elections held over the weekend but his supporters are challenging the result, which handed a win to incumbent Mahmoud Ahmadinejad.
Earlier this week the Metropolitan police said around 200 protestors had gathered for a peaceful protest against the election. Some held placards asking "Where is my vote?"
Smaller-scale demonstrations have taken place every night since then and a further protest is expected tonight.
