German carmaker BMW said it is continuing to prepare for a "worst-case scenario" no-deal Brexit after lawmakers voted to seek a delay to Britain's exit from the European Union.
BMW builds over 15% of Britain's 1.5 million cars.
It makes Minis at a factory in Oxford and Rolls-Royce models at a site in Goodwood in addition to more than 375,000 engines at its Hams Hall facility.
The firm said earlier this month that it could move some production out of Britain if the country does not secure an orderly departure from the European Union, another warning from a once soaring sector that is now reporting dips in investment, sales and output.
UK politicians voted overwhelmingly yesterday evening to seek a delay to Brexit, which is due on March 29.
"As a responsible employer, we must therefore continue to prepare for the worst-case scenario, which is what a no-deal Brexit would represent," a BMW spokesman said.
"In order to prepare for a postponement of Brexit, the BMW Group is currently examining various scenarios. Preparations cover all key areas of our business including manufacturing, sales, customs processes, IT and logistics," it added.
BMW's Mini and Rolls-Royce brands, Jaguar Land Rover and Honda - together accounting for around 55% of UK car output - all plan to shut their factories in April from between a week to up to a month in case of any disruption from a no-deal Brexit.
A delay would ruin such contingency plans as shutdowns are generally organised months in advance so employee holidays can be scheduled and suppliers can adjust volumes, making them hard to move.
