As part of the changes, sales and distribution director Chris Truscott will be leaving.

David Noyes, UK chief executive, said: “We have two leading brands and we need to differentiate between them. By bringing sales and marketing together we will bring a greater focus to each of our great brands."

Jeremy McKenna, head of partner sales will lead the agency sales team, currently for both brands, reporting directly to Ludlow in the interim period until the SVP Cunard sales and marketing role is appointed.

Carnival will also be recruiting for a sales and marketing role at Cunard.

Princess Cruises will be recruiting for Paul Ludlow’s replacement.

Ludlow said: “Following the launch of Britannia in March, which positioned P&O Cruises at the forefront of the nation’s mind, there has never been a more exciting time for the company.

“The potential for the industry as a whole is vast and I am determined, through giving a seamless, exemplary guest experience, working closely with our travel agent partners, to develop this growth to the maximum for P&O Cruises.”
