Reporting of actual events rather than the pre-announcing of announcements.
That really annoys me. "Such and such are set to announce something later today, we've got some people who were once involved in something similar to speculate on what might be said."
Although i've hated TV news presenters (they aren't journalists) for a long time, the election was the final straw. There was so little critical engagement with policies it was incredible. How often were the leaders pressed on what they would cut if they won?
So, another Radio 4 listener here. 5Live used to be interesting but then someone decided it was easier and cheaper to get people to ring in with ignorant opinions rather than pay for an expert's cab to the studio.
