Carmaker Honda is pausing production at its Swindon plant because of a shortage of stock caused by delays in getting parts into the UK.
The Japanese car giant said the decision on Wednesday (December 9) was "due to transport-related parts delays" as ports are hit by demand and coronavirus restrictions.
The plant operates on a "just in time" production system, where parts arrive as and when they are needed. Honda told employees that it is currently experiencing delays and congestion at UK ports.
"The situation is currently being monitored with a view to restart production as soon as possible," Honda told the BBC.
It added: "Honda of the UK Manufacturing has confirmed to employees that production will not run on Wednesday 9 December due to transport-related parts delays."
The company said it was looking at alternative arrangements, such as air freight.
The carmaker joins a growing number of businesses experiencing disruption at ports in the UK amid no-deal Brexit warnings.
In recent weeks congestion has been building up at a number of British ports, including in Felixstowe, Southampton and London Gateway.
Honda’s Swindon factory built just under 110,000 cars last year but is due to close permanently in 2021.
