Prime Minister David Cameron's official spokesman earlier declined to comment on whether the Government might back down on the 3p fuel duty rise.
He said the controversial rise was a matter for the Chancellor.
There are a series of planned rises in fuel taxes programmed in and those will generate revenue which will help bring the deficit down. But what the Government has sought to do thus far is listen to the concerns of motorists and, where it can, delay or cancel those planned rises.
Decisions on tax and duties are a matter for the Chancellor. The Government obviously recognises that the cost of petrol is a significant part of day to day spending and that is why (it) has listened to the views of consumers and motorists and acted over the past two years by delaying or cancelling planned rises.
