Rebekah Brooks has quit as chief executive of Rupert Murdoch's UK-based News International amid a widening scandal into phone hacking by journalists at the company's newspapers.
Brooks was the most senior executive at the company and is a former editor of both The Sun and the News of the World, the title shut down last week as a consequence of the scandal.
