As western governments struggle to keep a lid on fuel prices, the leadership of Iran faces a very different problem: its petrol is just too cheap.
Heavy state subsidies ensure that Iranian prices start at just $0.03 a litre, a fraction of the $1.10 paid at US pumps or the $1.88 that motorists in the UK are charged to fill their cars.
