The BBC has said that it “should have challenged” claims made by politician Lord Nigel Lawson contesting evidence about climate change.
The publication quoted the letter stating that Lord Lawson’s statements “were, at the least, contestable and should have been challenged”.
The Global Warming Policy Forum, a London-based campaign group chaired by Lord Lawson, later said on Twitter that his information was “erroneous”.
A spokeswoman for the broadcaster said that the latter comment referred to the content of Lord Lawson’s claims and added that there were other guests present on the programme that offered “different views”.
