Yep, they “found ‘corruption’”, therefore centralize. Kinda like what Obama wanted to do with local police.
Dont forget that a few years ago Putin suspended gubernatorial elections for the same reason (Constitutionally/legally, by the way, this isnt an arbitrary process). It was indeed, temporary, and governors are back to being elected. Government in general has improved by leaps and bounds in Russia during the last 10 years. Municipalities are the final frontier, and many are already on notice.
