Dreschler added that there is “zero evidence” that non-EU trade deals would help in any way, “It’s a myth,” he said.
Brexit has long been described as a threat to the UK’s car industry, with the Society of Motor Manufacturers & Traders (SMMT) claiming last year that damage has already been done, with domestic demand for UK-built cars falling across multiple months since the vote to leave the EU in June 2016.
Production figures recovered in April 2018, although 2018 so far remains down on the same period of 2017 by 3.9%.
“Real frictionless trade” is needed to prevent further damage to the UK’s car industry, said Dreschler, adding that the delays and increased costs from trade tariffs would be particularly damaging.
He said: ”We already know that hundreds of millions have been invested by UK pharmaceutical and finance companies to create continuity post a worse-case Brexit scenario. What could we have done with that money?"
A spokesman from the Government's Department for Exiting the European Union said: "We are focused on delivering a Brexit that works for the whole of the UK, including businesses across the economy.
"We have laid out our approach to our withdrawal and future relationship with the EU in 14 detailed papers we published last summer, numerous speeches given by the Prime Minister and cabinet ministers and the technical notes and slides we published in recent weeks.
