The Daily Telegraph
has an article about the increasingly conspicuous campaign to remove Putin's term limit:
The most recent backing for the idea came from Leonid Markelov, the president of the obscure semi-autonomous republic of Mari El. The fact that senior regional officials are now chosen by Mr Putin, rather than elected, may or may not have influenced Mr Markelov's position.
The main factor deterring Mr Putin from changing the constitution is the fear of the likely cool response from the West. The strategy could easily be compared with that of Alexander Lukashenko, the president of Belarus, described by President George W Bush as "the last dictatorship in Europe".
