Motorists under pressure will be relieved that the Prime Minister has committed the government to not increasing fuel duty.
The freeze on fuel duty, now frozen for its ninth year in a row, is set to cost the Treasury £38 billion if extended for the next three years.
But conversely, this represents tax savings of £38 billion for motorists.
Mrs May will formally announce the continued freeze in her speech to the Conservative Party conference.
Motoring interest groups have welcomed the announcement from the Prime Minister. RAC fuel spokesperson Simon Williams comments: “We are pleased the Prime Minister has listened to the RAC and millions of motorists by freezing fuel duty for another year.
“Drivers are currently paying the highest prices at the pumps for four years. While there is a silver lining in the form of no rise in fuel duty, darker clouds in the form of higher wholesale costs may well be passed on to drivers at the pumps imminently, so it would have been foolhardy for the Treasury to opt to punish drivers further.
“Motorists can breathe a sigh of relief for now. However, it is a shame that each year motorists have to worry whether the government is about to hit them harder in their pockets.”
