Graham Norton's chat show is to move to BBC1 as part of plans to raise the entertainer's profile as a face of the BBC, it wasda nnounced today.
However, the channel's controller insisted that the move was not a threat to Jonathan Ross, whose chat show is also on BBC1.
BBC1 controller Jay Hunt said that 'The Graham Norton Show' will move in the autumn from BBC2 to a 10.35pm weekday slot on BBC1.
The Irish entertainer recently provided the commentary for this year's 'Eurovision Song Contest', taking over from Terry Wogan.
Ms Hunt described Norton as a "unique talent" and said the changes would give him the chance to be the "zany person" people saw him as on Channel 4.
Ms Hunt said that the decision did not mean that Norton would have a mandate to be rude and vulgar.
She said Norton's repertoire was not all "dildo gags...Graham is fantastically good at engaging with audiences."
Ms Hunt said the changes would mean there were now "two compelling performers who will be regularly on at 10.35pm."
Ms Hunt said it had been Ross's decision to write his apology on the first episode of 'Friday Night With Jonathan Ross' following his suspension over the lewd calls to Andrew Sachs row.
She said: "Jonathan wrote that. I did not ask him to write that."
Ms Hunt said that since the scandal: "I haven't had any problems with him on my watch. I think he's done some fantastic interviews."
Last month, BBC Radio 2 began pre-recording Ross's shows on the station, and the presenter was said to be happy with the move.
Ms Hunt later added that negotiations had not begun with Ross yet on his next pay deal.
Speaking at a Broadcasting Press Guild event in London, the controller also outlined plans for a new science show called 'Bang Goes The Theory', which will feature new faces on TV carrying out ambitious experiments.
Ms Hunt said: "If we want to look like modern Britain we need authority figures who look and feel like they live in modern Britain."
