LONDON — He admitted that he and his colleagues hacked into people’s phones and paid police officers for tips. He confessed to lurking in unmarked vans outside people’s houses, stealing confidential documents, rifling through celebrity garbage cans and pretending that he was not a journalist pursuing a story but “Brad the teenage rent boy,” propositioning a priest.

After Paul McMullan, a former deputy features editor at Rupert Murdoch’s now-defunct News of the World tabloid, had finished his jaw-droppingly brazen remarks at a judicial inquiry on Tuesday, it was hard to think of any dubious news-gathering technique he had not confessed to, short of pistol-whipping sources for information.

Nor were the practices he described limited to a select few, Mr. McMullan said in an afternoon of testimony at the Leveson Inquiry, which is investigating media ethics in Britain the wake of the summer’s phone hacking scandal. On the contrary, he said, The News of the World’s underlings were encouraged by their circulation-obsessed bosses to use any means necessary to get material.

“We did all these things for our editors, for Rebekah Brooks and for Andy Coulson,” Mr. McMullan said, referring to two former News of the World editors who, he said, “should have had the strength of conviction to say, ‘Yes, sometimes you have to stray into black or gray illegal areas.’ ”
