Shortly after the arrest, a court sentenced him to 2½ years in prison for violating parole stemming from a 2014 suspended sentence in a fraud case Navalny said was politically motivated.

Its closest allies have left Russia after facing multiple criminal charges, and its Anti-Corruption Foundation and a network of nearly 40 regional offices have been banned as extremists – a designation that exposes the people involved in the lawsuits.
Earlier this month, Russian officials added Navalny and a number of his associates to a national register of extremists and terrorists.
Several criminal cases have been launched against Navalny individually, leading his associates to suggest the Kremlin intends to keep the politician behind bars for as long as possible.
