Given that Government Departments will spin data to optimise the whirlpool of political advantage, no official data on anything should be trusted without an independent audit. Even then the truth may be out there but finding it will need more than a spyglass.
A classic example of misinformation is the fishing dispute. Where is the truth? Both sides can't be right. It's about half truths and spin on both sides playing to the audience, instead of having an adult conversation , and an independent review.
The BBC and anyone else can only report what they are told, and sure journalists also spin news stories, so the whole system will never provide the whole truth on complex issues.
