Boulton has been at Sky News for 33 years, first serving as Political Editor until 2014 until becoming Editor-At-Large and presenter of the channel's All Out Politics programme.
Boulton has revealed that he will leave Sky News at the end of this year.
Speaking to The Times, Adam said: "…it’s a kind of mutual decision. Basically, just looking ahead, having been at two start-ups, first with TV-am and then Sky, I think it looks like the direction which Sky News wants to go over the next few years is not one that’s a particularly good fit for me."
Jon Ryley, Head Of Sky News, said: “Adam Boulton has been a hugely significant figure both in the growth of Sky News and British broadcasting as a whole. Adam was the first Political Editor to treat politics as a dynamic, changing story, combining live commentary with video. He also played a key role in bringing about the first televised leaders’ debates in 2010. I will miss his wise counsel.”
Sky News is available on Sky channel 501. All Out Politics airs weekdays at 11am.
