Crude oil is a key ingredient in petrol and diesel, which means that higher wholesale costs make filling up a car more expensive.

Analysts say every $10 (£7.53) increase in the oil price pushes up pump prices by roughly 7p a litre.

Since the war began, the price of a barrel of Brent crude – the global benchmark for wholesale oil prices – has been very volatile.

Before the conflict, Brent was about $70 a barrel, but the conflict saw it peak at above $120.

In early July, after the framework deal was signed, prices fell back to near the $70 a barrel mark, but have climbed back up again since to around $98 a barrel.
