Cunard UK sales director Gary Anslow is to leave the company after three years.
He has led the Cunard Partnership team but is leaving for another undisclosed role within the industry.
Bob Dixon, currently Cunard director EMEA and Latin America, will take on the UK role vacated by Anslow until a full time replacement is found.
Cunard said the changes are effective immediately.
Vice president marketing and UK sales, Angus Struthers, said: “I want to thank Gary for all his support and work in which we have seen the dedicated Cunard Partnership team establish itself as a highly regarded sales force amongst the cruise industry, and to welcome Bob who I know will do a sterling job leading the team in the coming months.”
