Sky News' executive editor, John Ryley (pictured), will succeed Nick Pollard as the head of Sky News in September.
Pollard is to leave his position after ten years leading Europe's first 24-hour news channel. The announcement of Pollard's departure comes eight months after the channel's expensive re-launch last October.
Pollard said: "Being head of Sky News, is in my view, the best job in broadcast journalism and I have had a fantastic ten years doing it. During that time Sky news has been the undisputed leader in continuous news."
In the decade in which Pollard led Sky News, the channel developed a reputation from breaking major news and events from around the world.
Under his leadership, Sky News was recognised for its live reporting from the field of events such as the Asian tsunami, the Iraq War and the Kosovo crisis when the channel was first with live pictures from inside Kosovo on liberation day.
Since the October relaunch, Sky has featured less rolling news and more distinct programmes plus the introduction of new presenters such as Eamon Holmes and James Rubin.
Sky's chief executive, James Murdoch, said: "Few people could claim to have done more than Nick Pollard to transform television news in this country. I have the deepest respect for Nick and the contribution he has made not only to Sky but to broadcast journalism as a whole."
