After surging 5p a litre in a month, the price of petrol at the pumps has gone up a further 1p in the last five days, the motoring organisation said.
It blamed a plunging pound and stock market speculators for the new rise, which has taken the average cost of petrol in the UK to 138.32p a litre, with diesel up 4.78p from mid-January to 145.10p. In Scotland, the average price of petrol is 137.8p.
