Journalist Nick Robinson is returning to the BBC to take over as political editor, replacing Andrew Marr who is stepping down from the job.
Robinson left the BBC in 2002
Robinson left the BBC in 2002 to join ITV News as its political editor. Before then, he had been BBC News 24's chief political correspondent.
He has also presented programmes for Radio Five Live and BBC Two.
Marr is quitting his post after five years to take over Sir David Frost's Sunday morning interview programme.
Robinson, who is a former deputy editor of Panorama and On The Record, also kept a regular Newslog column for the BBC News website before he left the corporation.
He has built up a reputation as a tenacious reporter.
'Excited and daunted'
Robinson said: "I've relished trying to give Andy Marr a run for his money over the past couple of years.
"I'm excited and daunted in equal measure at the prospect of now trying to fill his rather ample shoes.
"The job of BBC political editor is to bring drama, insight and analysis to a subject too many say they dislike but most know they simply cannot ignore. I can't wait."
Robinson began at the BBC in 1986 as a trainee producer on Brass Tacks, Newsround and Crimewatch.

He then moved into radio working on Five Live before going in front of the camera, presenting political review show Straight Talk and BBC Two's live coverage from Westminster.
BBC director of news Helen Boaden said: "I am delighted that Nick is joining the team.
"He brings incisive interviewing, a sharp questioning of authority and an ability to make politics and policy engaging to all audiences.
"I know that he will deliver original and accessible journalism across all of our services."
Robinson said he was sad to be leaving his old job at ITN, which produces ITV News.
"Rarely can anyone have taken a new job with such mixed emotions," he said. "I will miss ITN terribly. I have loved, and will continue to love, its chippy, cheeky, passionate approach to story-telling combined with vast pools of journalistic endeavour."
ITV News editor-in-chief David Mannion wished Robinson well, calling him "a quite exceptional journalist", but had harsh words for his new bosses.
He said: "It's astonishing that the BBC could find no-one amongst its vast army of journalists deemed good enough to be political editor and have poached back someone they failed to spot three years ago when he was under their very noses.
"We can only hope that the BBC will be bold enough to allow Nick the freedom to continue the iconoclastic and challenging style of journalism that ITN encouraged and which has made him such a success."
