Rebekah Brooks has been appointed Chief Executive Officer of News UK, News Corp have announced.
Last week it was announced that Ms Brooks was returning to Rupert Murdoch-controlled News Corp a year after she was cleared of phone hacking.
Brooks was found not guilty of all charges in the phone-hacking trial at the Old Bailey last year.
She told ITV News in June 2014 that she felt "vindicated by the unanimous verdicts".
Robert Thomson, the Chief Executive of News Corp said:
“I am delighted to return to News UK. It is a privilege to be back amongst the most talented journalists and executives in the business,” said Ms. Brooks.
“I am confident that we can meet the many challenges of this digital age with a combination of cutting edge technologies and world class journalism."
News Corp announced the appointment of Ms Brooks alongside several other leadership changes at the company, with former Daily Telegraph editor Tony Gallagher appointed editor-in-chief of The Sun newspaper.
The current editor of The Sun, David Dinsmore, has been promoted to Chief Operating Officer, News Corp said.
