Petrol prices have fallen but drivers are still being short-changed, according to the AA.
Average petrol prices have gone down from 138.95p a litre in mid October to 135.08p now, with diesel dropping from 143.74p a litre to 141.89p.
But the fall in wholesale petrol prices across Europe should have knocked UK pump prices down by 10p to 11p a litre, the AA said.
