But Nissan is fearing big tariffs.
"Of course. It's absolutely vital we protect supply chains, we protect Nissan Motors, we make sure people continue to want to invest in our country," Johnson said when asked if he could guarantee the future of Nissan's involvement in the UK. "As we come out it's all protected from the point of view of big motor manufacturing investors in our country."
Nissan, along with other car manufacturers either based or with operations in Britain, has repeatedly warned about the potential difficulties of a no deal Brexit, such as customs delays which could severely hamper supply chains.
Nissan Europe Chairman Gianluca de Ficchy told Automotive News Europe that if a hard Brexit leads to a 10 percent tariff on trade between the UK and the rest of Europe, the Japanese marque would have to reevaluate its position in the UK.
