Volkswagen owned Bentley is to cut 1,000 jobs in the UK, about a quarter of its workforce.
The company, which makes cars in Crewe, was expected to offer workers the chance to take voluntary redundancy, the BBC said.

Bentley declined to comment to the BBC.
Chief Adrian Hallmark said last month a quarter of the company's workers had been furloughed due to the lockdown while another quarter were working from home.
As first reported by ITV, the carmaker has since restarted production at its Crewe factory, but with only around half the usual number of staff.
Bentley, founded in the UK in 1919, increased its worldwide sales by 5% to 11,000 cars in 2019 but has struggled to be profitable in recent years.

By GlobalDataIt completed a turnaround plan last year but now appears to have been hit by the sharp fall in demand for new cars caused by coronavirus, the BBC said.
This has seen car manufacturers, suppliers and showrooms closed for weeks, with consumers holding off on big ticket purchases.
Car dealership Lookers announced on Thursday it would cut up to 1,500 jobs with the closure of more showrooms in the UK.
And Aston Martin also announced 500 redundancies on Thursday, a week after naming a new chief executive.
Union Unite described the Bentley announcement the company was seeking to make 1,000 workers redundant as another "heavy blow".
Bentley currently employs 4,200 workers at its factory in Crewe. The proposed 1,000 redundancies will be on a voluntary basis.
Unite's national officer for the automotive sector Steve Bush said: "This is another heavy blow for our automotive industry and its dedicated workforce.
"Bentley is a name known around the world for the quality of its vehicles, thanks in large part to the expertise of this highly dedicated and superb workforce.
"To ask 1,000 of them to leave the company, albeit on voluntary terms, is heartbreaking for the workforce and their communities. We are determined to support our members during this process to do what we can to mitigate the jobs lost.
"Unite will ensure that all our members are properly advised and supported throughout this highly stressful and traumatic time.
"Today's news is another sorry reminder of the battering this sector is taking, caught by a downturn in global demand which has then been supercharged by the global COVID-19 pandemic.
"It is absolutely essential that the government works with the automotive industry and Unite to bring forward the sort of sector specific support we are seeing other governments deliver, in France and Germany, because for every automotive job that goes, four more will go in the wider supply chain."
