A documentary investigating the death of PC Keith Blakelock in 1985 is among shows heading BBC Two's winter line-up.
PC Keith Blakelock was murdered in 1985
The channel announced details of the programme the day after Scotland Yard announced a fresh inquiry into the case
Other highlights of the season will include What The World Thinks Of God, a follow-up to the 2003 show What The World Thinks Of America.
Viewers will also be invited to vote for Britain's Best Sitcom, hosted by Jonathan Ross.
The Blakelock documentary promises extensive interview footage with Winston Silcott, who was convicted of the murder in 1987 but whose conviction was later overturned.
"Who Killed PC Blakelock? promises to be a gripping and relevant watch," said BBC Two controller Jane Root.
It is part of a season that focuses heavily on documentaries, history and current affairs.
Major new series include Third World War, which promises to be "the most authoritative and revealing account to
date of the secret war between the Western intelligence agencies and Al Qaida's networks".
Docu-dramas about Professor Stephen Hawking and the 1940 battle of Dunkirk, here told through the eyes of Allied soldiers and British army leaders, are also promised.
Meanwhile Robert Carlyle heads the cast of Gunpowder Treason and Plot, a historical drama from writer Jimmy McGovern.
Jonathan Ross will host Britain's Best Sitcom
And current affairs programme Correspondent will be replaced by a new programme, This World.
Lighter entertainment will include The Sack Race, in which a bunch of comedians posing as employees compete to see who can be sacked from a new job on the first day.
And My Life In The Real World - in which politicians try alternative jobs - will return, following an initial episode in which Michael Portillo became a single parent for the week.
This time, former overseas development minister Clare Short will become a geography teacher in a south London comprehensive, while Tory MP Alan Duncan will take a group of children from a council estate on an outward bound course.
Britain's Best Sitcom, hosted by Jonathan Ross, will start by counting down
the top 50 shows.
Viewers will then be asked to choose between the top 10 TV classics and the
number one will be revealed in a live special.
Each show in the top 10 will be the subject of an hour-long programme
featuring a celebrity advocate, in the style of The Big Read and Restoration.
