In Russia nothing changes, its just less messy

Russia will have a coup when Putin steps down as President.

He will become Prime Minister.

Thus his puppet for President will allow Putin to continue running the country but as Prime Minister and not as President although he will be "de facto" President and Prime Minister.

While losing the title of President and taking the lesser job Putin is in fact increasing his power rather than decreasing it.

It is a coup, a legal and very tidy one. So just like the old days a dictatorship is established but without having to kill or repress anyone or close parliment or put troops on the streets.

In Russia nothing changes, its just less messy these days.
