LONDON ¨C Nissan said it would take legal action against the official campaign for Britain to leave the European Union after the group used the Japanese carmaker¡¯s logo in leaflets calling for voters to back Brexit on June 23.

On one ¡°Vote Leave¡± flyer, the firm¡¯s logo appeared next to those of four other major companies, including Unilever and fellow carmaker Vauxhall with the message: ¡°Major employers ... have all said they¡¯ll stay in the UK whatever the result of the referendum.¡±

Nissan, which says it would prefer Britain to remain in the EU, said it would be issuing legal proceedings on Monday in Britain¡¯s High Court to stop ¡°Vote Leave¡± from using its name and logo and to ¡°prevent them making any further false statements and misrepresentations concerning Nissan.¡±

¡°We vigorously protect the Nissan brand and intellectual property in all markets in which we operate,¡± the firm said in a statement.

Nissan said earlier this month that it was considering legal action against the official campaign, a day after rival Toyota said it could also make a legal complaint.

On Monday, a spokesman at Toyota said the firm¡¯s position had not changed.

Consumer goods maker Unilever has also complained to the ¡°Vote Leave¡± campaign over the use of its name and logo.

On Monday, several carmakers repeated their calls for Britain to remain in the 28-member bloc, with access to the single market benefiting major firms.

In a letter to staff, Toyota¡¯s U.K. managing director warned that leaving the bloc would impose duties on cars of up to 10 percent, forcing the firm either to make cuts or raise prices, negatively impacting sales.

¡°If the U.K. leaves the EU, we think it unlikely that the U.K. can keep the current trading arrangements where there are ¡®no tariffs or duties,¡¯ ¡± Shigeru Teramoto wrote in a letter jointly signed by a British trade union official.
