Tory MPs are demanding an assurance from Chancellor Jeremy Hunt that he will not go ahead with a planned rise in fuel duty following a warning it would add 12p to the price of a litre of petrol or diesel.
In its latest economic forecasts, the Office for Budget Responsibility (OBR) noted that the rise – which is pencilled in for next March – would bring in a record cash increase of £5.7 billion if it goes ahead.
