P&O (in full, The Peninsular and Oriental Steam Navigation Company) is a British shipping and logistics company dating from the early 19th century. Formerly a public company, it was sold to DP World in March 2006 for £3.9 billion. DP World currently operate several P&O branded businesses, P&O Ferries, Istithmar P&O Estates, and P&O Maritime Logistics. It also operates P&O Heritage, which is the official historic archive and collection of P&O. P&O Cruises was sold in 2000, and is now owned and operated by Carnival Corporation & plc. The former shipping business, P&O Nedlloyd, was bought by and is now part of Maersk Line. History Early years and expansion: 1822–1900 In 1822, Brodie McGhie Willcox, a London ship broker, and Arthur Anderson, a sailor from the Shetland Isles, went into partnership to operate a shipping line, primarily operating routes between England and Spain and Portugal. In 1835, Dublin shipowner Captain Richard Bourne joined the business, and the three men chartered the William Fawcett and started a regular steamer service between London and Spain and Portugal – the Iberian Peninsula – using the name Peninsular Steam Navigation Company, with services to Vigo, Oporto, Lisbon and Cádiz. As The Peninsular and Oriental Steam Navigation Company was incorporated in 1840 by a royal charter its name therefore included neither "plc" nor "Limited". The company flag colours are directly connected with the Peninsular flags: the white and blue represent the Portuguese flag in 1837, and the yellow and red the Spanish flag. At the height of the Carlist Wars the British lent their support to the legitimate heirs of Spain and Portugal and all three of P&O founders played their part, from gun running to chartering steamers. As a consequence of this association and involvement P&O officers are some of the few Merchant Navy officers entitled to wear swords, alongside the likes of Trinity House. In 1837, the business won a contract from the British Admiralty to deliver mail to the Iberian Peninsula and in 1840 they acquired a contract to deliver mail to Alexandria in Egypt. Brindisi, Italy was added to the route in the 1870s. P&O first introduced passenger services in 1844, with a leisure cruise departing from Southampton to the Mediterranean. These voyages were the first of their kind and the forerunner of modern cruise holidays. The company later introduced round trips to destinations such as Alexandria and Constantinople and underwent
