The War on Science:

Opponents of global warming should be given less coverage by the BBC than the climate change lobby, the corporation will rule.

The BBC is set to publish a report tomorrow on its science output announcing changes to rules on impartiality.

Following the overhaul, programme makers and broadcasters will be compelled to give less prominence to those who oppose the scientific community's majority view.

According to the Daily Telegraph, the report draws heavily on an independent review of BBC coverage by Steve Jones, a professor of genetics at University College London.

Professor Jones is understood to have cleared the BBC of any suggestion of bias in its programming.
