LONDON (AP) — Rupert Murdoch’s scandal-hit News International confirmed Tuesday it is reviewing journalistic standards across the company, a U.K. media empire that includes The Times of London newspaper.

The British newspaper arm of Murdoch’s global empire has been shaken by widespread allegations of illegal behavior at the now-defunct News of the World tabloid, once Britain’s most popular Sunday paper. More than a dozen News of the World journalists and executives have been arrested over claims that they systematically intercepted mobile phone messages and illegally paid police for tips.

Allegations of wrongdoing at other U.K. newspapers have since spread a cloud of suspicion over the entire U.K. media industry. The publishers of the Daily Mirror and the Daily Mail, which both compete with Murdoch’s papers, have announced their own, separate reviews of editorial procedure in the wake of the scandal.

An independent inquiry led by a British judge is also due to put the country’s press under the microscope beginning next month.

In a statement, News International said its internal review was launched “a number of weeks ago” and was being carried out with the assistance of London law firm, Linklaters.
