News Corp UK & Ireland Limited is a British newspaper publisher, and a wholly owned subsidiary of the American mass media conglomerate News Corp. It is the current publisher of The Times, The Sunday Times, and The Sun newspapers; its former publications include the Today, News of the World, and The London Paper newspapers. It was established in February 1981 under the name News International plc. In June 2002, the company name was changed to News International Limited, and on 31 May 2011, to NI Group Limited, and on 26 June 2013 to News UK.

The News of the World was a weekly national "red top" tabloid newspaper published every Sunday in the United Kingdom from 1843 to 2011. It was at one time the world's highest-selling English-language newspaper, and at closure still had one of the highest English-language circulations. It was originally established as a broadsheet by John Browne Bell, who identified crime, sensation and vice as the themes that would sell most copies. The Bells sold to Henry Lascelles Carr in 1891; in 1969, it was bought from the Carrs by Rupert Murdoch's media firm News Limited. Reorganised into News International, a subsidiary of News Corporation, the newspaper was transformed into a tabloid in 1984 and became the Sunday sister paper of The Sun.
