Princess Cruises

On October 23, 2000, the Peninsular & Oriental Steam Navigation Company (P&O) spun-off its passenger division to form an independent company, P&O Princess Cruises. The company subsequently merged with Carnival Corporation on April 17, 2003, to form the world's largest cruise operating company in a deal worth US$5.4 billion. As a result of the merger, Carnival Corporation and P&O Princess were integrated to form Carnival Corporation & plc, with a portfolio of eleven cruise ship brands. It is a dual-listed company, registered in both the United States and the United Kingdom, with the former P&O Princess Cruises being relisted as Carnival plc, more commonly known as Carnival UK. As an American-based company, executive control of Princess Cruises was transferred to Carnival's American operations, with Carnival UK taking control of Southampton-based Cunard Line. Princess and Cunard have offices at Carnival's head offices in both the United States and the United Kingdom.
