Jaguar Land Rover has said it's important the new Brexit deal "protects tariff-free and frictionless trade and guarantees a level playing field on critical areas of regulation and immigration."
But a statement from the company said it was still considering the details of the latest deal would not be commenting further until MPs vote on it tomorrow.
Boris Johnson's deal commits Britain and the EU to work towards a Free Trade Agreement and also says the UK and the EU should "uphold the common high standards... in the areas of state aid, competition, social and employment standards, environment, climate change, and relevant tax matters".
Mike Hawes, the chief executive of the Society of Motor Manufacturers and Traders welcomed the deal, and said it "moves us further away from a damaging no-deal Brexit" but he was also cautious about possible future regulation.
He added: "To give the UK automotive industry certainty, however, and to assure its continued global competitiveness, we need a truly ambitious future relationship – one based on tariff-free and frictionless trade."
