Jailed Russian opposition politician Alexei Navalny said on Wednesday he had been moved to a harsher "cell-type" regime of solitary confinement for the next six months where he would be denied visits.
Navalny, 46, is the highest-profile of the few remaining opposition voices in Russia, having gained followers with repeated investigations purporting to show that the ruling class had enriched itself lavishly at the expense of the state.
