It is in the nature of British politicians to meddle with satisfactorily operating organisations in order to show that they are in control. You have only to look at the number of reorganisations and "initiatives" taken in the NHS. Some, after a change in governing party, before any opportunity for the previous changes to show any effect.
It happens with education, too. We now have a Secretary of State who is so mathematically illiterate that she considers it possible for all schools to be "above average".
The BBC is equally vulnerable. Changes to the BBC may well be the result of politicians taking part in a hairy chest competition.
I would not suggest that the BBC should not subject to critical examination, but there is something which the meddling politicians ought to consider. The BBC is probably the only British brand which isn't just world class - but top world class. Any reduction in the world's perception of the BBC will directly affect the perception of Britain itself.
We have a government system that believes that the highest artistic, cultural and intellectual achievement of human kind has been the invention of cost accounting. And we have a prime minister who barely adequate to the task of governing, who is more concerned with the state of his party than of the nation. He is constantly looking over his shoulder - in fear of the paeliolithic throwbacks his party always attracts.
