LONDON — Long lines of cars choked roads outside gas stations in Britain, as some waited for hours to fill up their tanks despite pleas from officials not to panic buy fuel.

“Sorry, out of use,” yellow signs told drivers looking for petrol over the weekend, as some pumps ran dry even as the British government assured that there was no shortage – but rather a delivery problem.

Gas – or petrol – is only the latest key item that Britain is struggling to obtain. The shortages are largely due to supply chain disruptions from the coronavirus pandemic, which exacerbated problems spurred by Britain’s exit from the European Union.
