Carmaker Toyota Motor said it could make a legal complaint against the official Brexit campaign for using its logo in leaflets, which the Japanese firm said might give the impression it backed Britain leaving the European Union.

On one Vote Leave flyer, Toyota’s logo appeared next to those of five other major companies, including fellow automakers Nissan Motor and the Vauxhall unit of General Motors, with the message, “Major employers ... have all said they’ll stay in the U.K. whatever the result of the referendum.”

Toyota, which built more than one out of 10 of Britain’s 1.6 million new cars last year, said in February it believed a vote June 23 to stay in the bloc would be better for its operations and long-term competitiveness.

The firm said Thursday that the use of its logo could “mislead the reader into thinking that Toyota endorses the Vote Leave campaign” and that it could take action against “unauthorized use of our trademarks.”

Vote Leave did not immediately respond to a request for comment when contacted by Reuters.

Britain’s overwhelmingly foreign-owned car industry has spoken out in favor of continued British membership in the EU, which allows it to benefit from tariff-free access to the single market and the free movement of people within the world’s biggest trading bloc.
