Bernard Bradley, general manager of Honda UK, is to leave the role after three years to pursue new opportunities in the Middle East.
In the short term, Tom Gardner, head of marketing for Honda cars, has agreed to assume responsibility for the company’s car operation while continuing to perform his current duties.
Honda UK said an announcement on Bradley’s successor would be made “in due course”.
Bradley said: ”Leaving Honda has been an extremely difficult decision to make. I've enjoyed the challenge of strengthening Honda’s relationship with its dealer network and the opportunity to work with a number of very talented people inside the company.
“I'll miss everyone’s exceptional drive to achieve and wish Honda and the dealer network every success for the future."
