UK car production fell by almost 10 per cent last month, with 15,200 fewer vehicles produced compared with the same month last year, new figures show.
The Society of Motor Manufacturers and Traders (SMMT) blamed the decline on uncertainty over Brexit, "market turbulence" in the UK and overseas, and changes of car models.
Production for the UK market fell by 12 per cent, the fifth consecutive month of decline.
Overseas demand was down by 9 per cent, although exports accounted for four out of five cars manufactured.
Around 1.3 million cars have been built so far this year, 6.9 per cent fewer than the same period last year.
Mike Hawes, SMMT chief executive, said: "The fifth consecutive month of decline for UK car manufacturing is undoubtedly concerning and, while a number of factors have been at play, there is no doubt that business and consumer uncertainty is having a significant impact.
"With eight in 10 British-built cars destined for overseas markets, the majority to the EU, the sector's dependence on exports cannot be downplayed.
"Europe is our largest trading partner and securing the right Brexit agreement which allows free and frictionless trade is vital for the future health of our industry."
