Stellantis is threatening to kill production in the UK, saying the country has set very high sales targets for electric cars.

The goals of selling zero-emission cars are not compatible, said Maria Grazia Davino, the company’s regional manager, told the media on Tuesday. The comments come as the UK heads to a general election on July 4 in which the incumbent Conservative and Labor parties are determined to stick with current electricity sales targets.

The UK has introduced rules requiring 22% of each manufacturer’s new car sales to be imported this year, rising to 80% by 2030. For vans, 70% of new sales should be electric during that time.

With demand for EVs slowing, Davino said Stellantis would be forced to make discounts to meet the standards that risk fines of up to £15,000 ($19,022) per vehicle for those who fail to comply. The workers have pledged to keep their mandate in place if they win the national election next week.

Stellantis makes electric vans for all its Vauxhall, Citroen, Peugeot, Opel and Fiat brands at its site in Ellesmere Port, following a £100 million investment to convert the factory into an electric facility only last year. The company also manufactures medium vans in Luton near London.

“We have invested heavily in Ellesmere Port and Luton with more to come,” Davino said at the SMMT International Automotive Summit in London. “But if this market hates us, we will go into production elsewhere.”

This is not the first time that Stellantis has threatened to leave the UK. Last year, the company warned that it would close factories unless the prices of its electric vans exported to the European Union were renegotiated. An agreement between the EU and the UK was finally reached before the deadline.

Stellantis is warning about UK EV sales targets as consumer demand has weakened in recent months amid persistent price hikes and unclear charging infrastructure. Davino said higher targets for 2030 “could be very damaging.”

“If demand doesn’t keep up with supply, we will be forced to make decisions – because we control profit and loss, we manage operational decisions – that affect the UK,” he said.

When asked how long Stellantis, the UK’s best-selling van manufacturer, could continue without changes at work, he said: “Less than a year.”

Stellantis sold around 216,000 new cars in the UK last year, accounting for 11% of the total market, including more than 100,000 under the Vauxhall brand.
