Of course, there's no real indication from Sunak what he actually means by that. It's posturing, avoiding making any decisions about the BBC as he's worried that might lose votes, and trying to sound tough as he might lose votes if he doesn't. I suppose we shouod be glad that at least it's not corrupt, or blatantly idiotic, or both.
