Luxury cruise brand Cunard today announced it is adding a fourth ship to its fleet.

Carnival Corporation - the world’s largest cruise company and parent of the Cunard brand - has signed a memorandum of agreement with Fincantieri, Italy, to build a new ship that will join the Cunard fleet in 2022.

The as yet unnamed ship will join Queen Mary 2, Queen Victoria and Queen Elizabeth as the fourth member of the Cunard fleet, the first time since 1998 that the luxury cruise brand will have four ships in simultaneous service.

The iconic cruise brand is going from strength to strength, having seen crowds of more than one million people gather in 2015 to celebrate the company’s 175th anniversary.

Cunard has subsequently invested over £120 million refurbishing the flagship Queen Mary 2 and Queen Victoria.
