Scott said: "This is a significant time for the travel industry and particularly the cruise sector, as we begin the initial phase of our return to service with the UK coastal cruises. The arrival of our two new ships for P&O Cruises in the next 18 months, Iona and Arvia, gives us huge scope to encourage a new audience to cruising and travel agents will play a critical role in this future growth.
“I am looking forward to playing a part in the recovery of the industry in the coming years, through listening to our guests, working closely with our travel agent partners and continued investment in our ships."
Ludlow added: “Robert’s varied and proven sales and marketing expertise will stand us in good stead as we embark on our resumption of sailing at this milestone time for the industry as whole.
“His experience with blue chip companies will ensure that hand in hand with our agent partners we will create stand out communication and strong commercial partnerships for our mutual benefit."
