stellantis the world’s fourthbiggest carmaker by sales has warned of a potential existential threat to large parts of the british car industry unless the government moves to alter the terms of its brexit trade deal with the european union in a submission to a parliamentary inquiry into the supply of batteries for electric vehicles released wednesday the parent company of citroen fiat peugeot and vauxhall said it may not be able to keep its commitment to manufacture its new fleet of cars in the uk without changes to the terms of the deal stellantis stla stlam said the deal represented a “threat” to its export business and the “sustainability” of its manufacturing operations the company employs around 5000 people in the uk and committed to make electric vehicles in the country two years ago the stark warning is likely to pile pressure on the conservative government to seek changes to the trade deal that came into force at the start of 2021 when the uk formally left the economic structures of the eu including the frictionless single market and customs union executives from stellantis are due to meet with britain’s business secretary kemi badenoch on wednesday though the trade deal ensured that tariffs would not be slapped on the export of goods from the uk to the eu an array of oftencomplex nontariff barriers has made it more difficult and often more costly for british businesses to sell their wares in the 27nation bloc some of these barriers are being phased in over time as a result stellantis said it wanted the current phasein period for the requirement to be extended until 2027 a move that would require the trade deal to be revised the company said cars made in britain and exported to the eu faced an onerous effective 10 tariff making them uncompetitive against exports from other major carproducing regions such as japan and south korea “to reinforce the sustainability of our manufacturing plants in the uk the uk must consider its trading arrangements with europe” stellantis said in its submission “we need to reinforce the competitiveness of the uk by establishing battery production in the uk” the leader of the main opposition labour party keir starmer said the postbrexit trade deal needed revision but insisted he wasn’t calling for the uk to rejoin the eu or its frictionless economic arrangements “that doesn’t mean reversing the decision and going back into the eu but the deal we’ve got it was said to be ovenready it wasn’t even halfbaked” he told the bbc in 2016 the uk narrowly voted to leave the eu in a referendum a general election has to take place by early 2025 with opinion polls suggesting labour is on course to be the largest party in parliament
