The BBC's flagship television current affairs programme Panorama is to return to peak time transmission.
From January it will be shown at 8.30pm on Monday on BBC1, taking it back to a regular weekday slot, which it occupied before its move to Sunday evenings in October 2000.
There has been some criticism over the years since its move about it being on in what is sometimes seen as a "graveyard" slot.
A BBC spokesperson said there would be 48 30-minute episodes a year and four one-hour specials.
The programme is usually 40 minutes long.
BBC1 controller Peter Fincham said: "This is the right move for BBC1 and I'm really excited about it.
"In its new slot, Panorama will continue to be the flagship of serious, rigorous, trustworthy journalism on the channel, covering a range of topics.
"The programmes will look to engage audiences, producing reports that resonate with viewers.
"Original, investigative journalism from reporters of real calibre will remain a vital ingredient of the programme."
Launched on Wednesday November 11, 1953, Panorama is the longest-running public affairs television programme in the world.
Initially it was broadcast fortnightly but switched to a weekly screening in September 1955, when it started transmitting on Monday evenings at 8.15pm.
