Diesel is almost £2 per litre in the UK, the highest price ever. The latest average cost – 199.18p – has edged past the 199.09p of June 2022, following the Russian invasion of Ukraine, said the RAC.

This is “uncharted territory”, an expert told City A.M. Donald Trump has already sent markets into a “frenzy” by threatening to ban diesel exports from the US, said the same paper. Weakened infrastructure for refining diesel and lower reserves than European counterparts mean the UK could be uniquely “exposed” to any further “ripple effects”, including more price rises.
