named News UK. Operations The company's major titles are published by subsidiary companies, Times Newspapers Ltd and News Group Newspapers. Until 2010, these newspapers were written at a large site in Wapping in east London, near Tower Hill, which earned the nickname "Fortress Wapping" after a fierce dispute with the union to which the workforce had previously belonged. The printing of the papers is now undertaken at plants in Waltham Cross, Knowsley, and Lanarkshire (the latter said by Rupert Murdoch, on the plant's opening in 2007, to be "the largest and fastest print press in the world").
