President George W Bush has called on Congress to end a 27-year ban on drilling for oil in US coastal waters, to reduce dependence on imports.
Mr Bush said existing restrictions on offshore drilling were “outdated and counter-productive”.
His move comes as US consumers are calling for action to tackle high oil prices that have pushed prices at the pump to more than $4 (£2) a gallon.
US energy needs are set to be a key issue in November’s presidential poll.
