LONDON — A lawyer representing some of Britain’s phone hacking victims said on Friday that he was planning legal action in the United States against the News Corporation, the parent company of Rupert Murdoch’s global media empire.

In a series of interviews in London, the lawyer, Mark Lewis, said he had held discussions with American lawyers about the steps necessary to open proceedings against the News Corporation in New York, and that he expected the process to begin soon. He said he had hired Norman Siegel, a New York lawyer who has represented many of the families of those killed in the terrorist attacks on Sept. 11, 2001, to handle the case.

In an interview with Sky News, a British television network that is part of the Murdoch empire, Mr. Lewis said that the legal action in the United States would focus on the “News Corporation’s liability for actions by its foreign subsidiaries,” including the tabloid The News of the World, which has been at the center of the phone hacking scandal and was closed in July. He said the lawsuits would focus on the revelations of widespread phone hacking in Britain and on accusations that the police were bribed to assist in the tabloid’s pursuit of scoops.
