ITV news editor Deborah Turness has announced her decision to quit after being offered the position of president of NBC News, New York.
Turness has been in the editorial hot seat at ITV since 2004 when she became the first female, and the youngest person ever, to take on the role.
Career highlights include a number of world exclusives; such as the arrest of the 21/7 bomb plotters, a leaked report on the shooting of Jean Charles de Menezes and the Jimmy Savile abuse scandal.
ITV's director of news and current affairs, Michael Jermey, said: “Deborah has made an enormous contribution to ITV News over many years and we wish her all the very best in her new role.
“She leaves ITV News in great shape.
“Her successor will take on the leadership of a highly talented team with a great track record in making award winning programmes.”
Turness added: “It is quite simply the greatest imaginable honour to be named as the next president of NBC News.
“I am hugely excited by the opportunities that lie ahead and look forward to working with the talented journalists and technicians who make it one of the great global news operations.
“I owe so much to ITN for nearly 25 fabulous years of adventures and challenges.”
Turness will remain at ITV News until July.
