Former showbiz reporter Victoria Newton has been appointed editor of The Sun On Sunday.
The 41-year-old, who was deputy editor of the News Of The World when it was closed in July 2011, takes over 18 months after the launch of the Sunday paper.
Until her new appointment, she had been deputy editor of The Sun's seven-day operation and she will continue to report to David Dinsmore, the overall editor of the titles.
Newton's role is part of an investment push for the Sunday paper with a new marketing campaign, the appointment of columnist Tony Parsons and the hiring of more journalists.
The Cambridge-educated journalist began her career at The Express and moved to The Sun as a showbiz reporter. She was also the paper's Los Angeles correspondent and went on to become showbiz editor at the Daily Mail before returning to The Sun as the editor of long-running showbiz section Bizarre, and later head of features.
She returned to The Sun two years ago, shortly after the NOTW closure. Until now, the Sunday edition had come under the authority of The Sun's editor.
Newton said she was "thrilled" by her new role and added: "The Sun has a formidable reputation for exclusive, hard hitting and investigative journalism and alongside the humour and headlines, showbiz and comment I look forward to securing The Sun firmly as the home of the best Sunday stories."
Dinsmore said: "Victoria is ideally placed to build on the Sun's long-standing success and ensure our readers our amused, informed, provoked and championed every Sunday, as they are during the week."
