LONDON (Reuters) - With his hands on all the levers of power in Russia, Vladimir Putin appears unbeatable in a presidential election but opposition activists scent a chance to show he is vulnerable.

Putin declared his candidacy for another six-year term on Friday and there is no serious rival to challenge him, with opposition leader Alexei Navalny serving more than 30 years in prison and other critics also jailed or in exile.
