Motorists have had their hopes of avoiding another petrol pump increase later this year dashed by Chancellor George Osborne.
Motoring organisations had wanted Mr Osborne to defer the planned August fuel duty rise in Wednesday's Budget.
But he said there would be no change to existing fuel duty plans. He added that vehicle excise duty (VED) would rise by the rate of inflation, although it would be frozen for hauliers.
Road users are already forking out for record petrol and diesel prices and today's announcement from Mr Osborne was greeted with dismay by motoring groups.
AA president Edmund King said: "At a time of record prices at the pumps the August increase in duty is a budget blow-out which will force drivers off the road and could bring a summer of discontent for many.
"We have heard much about tax allowances but the increase in fuel duty makes no allowance for car-dependent, rural and disabled drivers.
"Only last week the Prime Minister told American students that UK fuel prices would make them 'faint', yet the Government seems intent on inflicting more pain for no gain on drivers.
"Ironically such a hike in duty doesn't necessarily help Government finances as people will cut spending at the pumps and in shops, and it could fuel inflation."
