Britain's Sky News says Honda is to close a car factory in western England with the potential loss of 3,500 jobs.

The broadcaster says the Japanese carmaker will announce Tuesday that the Swindon plant, where Honda makes its Civic model, will close in 2022.

Honda said Monday it could not comment "at this stage." The Unite trade union, which represents workers at the plant, said it was looking into the report.

The report comes as British businesses are issuing increasingly urgent warnings about the damage being done by the uncertainty around Britain's looming exit from the European Union.

The U.K. is set to leave the bloc on March 29 but has yet to seal a deal laying out the divorce terms and establishing what trade rules will apply after Brexit.
