Washington Post Publisher and Incoming Editor Are Said to Have Used Stolen Records in Britain

The publisher and the incoming editor of The Washington Post, when they worked as journalists in London two decades ago, used fraudulently obtained phone and company records in newspaper articles, according to a former colleague, a published account of a private investigator and an analysis of newspaper archives.

Will Lewis, The Post’s publisher, assigned one of the articles in 2004 as business editor of The Sunday Times. Another was written by Robert Winnett, whom Mr. Lewis recently announced as The Post’s next executive editor.

The use of deception, hacking and fraud is at the heart of a long-running British newspaper scandal, one that toppled a major tabloid in 2010 and led to years of lawsuits by celebrities who said that reporters improperly obtained their personal documents and voice mail messages.

Mr. Lewis has maintained that his only involvement in the controversy was helping to root out problematic behavior after the fact, while working for Rupert Murdoch’s News Corporation.

But a former Sunday Times reporter said on Friday that Mr. Lewis had personally assigned him to write an article in 2004 using phone records that the reporter understood to have been obtained through hacking.

After that story broke, a British businessman who was the subject of the article said publicly that his records had been stolen. The reporter, Peter Koenig, described Mr. Lewis as a talented editor — one of the best he had worked with. But as time went on, he said Mr. Lewis changed.
