Oil prices have soared amid concerns over the reliability of supplies due to Russia’s invasion of Ukraine, causing the cost of petrol to skyrocket.

The price per barrel of Brent crude – the most commonly used way of measuring the UK’s oil price – reached 139 US dollars on Monday, which was its highest level in 14 years.

RAC fuel spokesman Simon Williams said: “The cost of a filling a 55-litre family car with petrol is now £87 – £7 more than it was at the start of the year.

“Diesel drivers are even worse off, with a tank now costing more than £90 for the first time ever – £8 more than in early January.

“Wholesale fuel prices have already risen dramatically this week, so more pump price increases in the coming days are inevitable.

“Petrol is now certain to top an average of £1.60 a litre this week, while diesel will progress very quickly towards £1.70.
