Chris Evans is to make his return to television as host of The One Show on Friday nights.
The Radio 2 breakfast DJ will replace Adrian Chiles, who will continue to present the hit BBC1 programme from Monday to Thursday. Evans will present a new extended Friday edition beginning this summer.
The appointment comes more than a decade after Evans resigned from Radio 1 on air after the BBC station refused to let him have Fridays off to present Channel 4's TFI Friday.
Reports that BBC executives wanted Evans, 44, to take over from Chiles, 43, on Fridays, alongside Christine Bleakley, 31, in a more entertainment-led show, first emerged last autumn.
Chiles was reported to have turned down an offer to move to ITV after news of the potential Evans move to The One Show was leaked.
Chiles is yet to sign a new BBC deal, but he is likely to stay on the show, with Evans hosting on Fridays.
The One Show launched on the BBC four years ago, with ratings rising steadily to 7.4 million in January.
Evans, whose last regular TV presenting job was hosting OFI Sunday for ITV in 2005, took over from Sir Terry Wogan on Radio 2's weekday breakfast show in January, a move which is said to have boosted audience figures.
Evans said: "I think what Adrian and Christine have done with the show is fantastic.
"It has become a much-loved institution in a relatively short space of time and I am honoured to be able to be joining the team."
The former TFI Friday host added: "For me Fridays have always been a little bit special and I want to do my bit to welcome people to the weekend."
BBC1 Controller Jay Hunt said: "The One Show is without doubt one of our most popular programmes and I am thrilled that Chris will be joining such a successful team.
"His unique presenting style and infectious enthusiasm will be a great addition to the show."
The hour-long Friday show will feature the regular mix of news, current affairs and entertainment alongside some new features and guest slots.
