Car maker Nissan is taking legal action against the official Vote Leave campaign group over use of its company logo.
The Japanese manufacturer is taking its case to the High Court after the Brexit campaign continued to feature the automaker's trademark in its referendum leaflets despite being asked to stop.
Nissan is seeking an injunction to stop Vote Leave making "any further false statements" during the final days of the referendum campaign.
The company said it was "extremely disappointed" the Leave campaign used its name in its campaign materials that "grossly misrepresents" its position on the June 23 vote.
A Nissan spokesman said: "We vigorously protect the Nissan brand and intellectual property in all markets in which we operate.
"We have repeatedly asked Vote Leave to stop using our name and logo on their materials and to stop misrepresenting our views - a request that has clearly been denied."
