Jailed Russian opposition leader Alexei Navalny revealed that he was transferred to a solitary confinement cell for 12 days for swearing.

Writing about his experience on Twitter, Mr Navalny said he was released from the punishment cell on Monday only to be locked up again a day later.

“My latest break from the punishment cell didn’t last long - exactly one day. I was released on Monday, and then locked up again yesterday. This time I got 12 days for “using the word ‘f***’ (sorry) in a conversation with a cellmate,” he wrote.
