The UK has a problem of local news
We don't have many areas that can have a successful market for local news. The same problem we have with government, that the country is just physically small enough that government suffers from the delusion that centralisation can be successful. Without local news though, you can't really have effective local democracy. Admittedly that also requires voters to give an effective damn about local news, local democracy and bother to vote and stuff.
It's a real chicken-and-egg situation. If councils don't have power, people won't vote. But if you devolve them power when people aren't voting, you get corruption and stupid decisions. And if nobody's interested, no-one's reading the local press, so there's no scrutiny.
We had reasonably representative local government 100 years ago. You could get from being a leader of say Birmingham council to being a senior national politician in one step back then. Because the role had a profile. Maybe city mayors will make a difference here?
it's a really dull subject - and that's the problem. Because nobody will take it seriously. But it actually matters quite a lot. Otherwise local government just becomes a playground for non-serious politicians to push their pet projects, in a lot of cases in safe seats with little risk of getting turfed out by voters.
