BBC's Sarah Rainsford on Alexey Navalny:
'When #Navalny survived the attempt to kill him with a nerve agent, #Novichok , he knew he would never be safe again in #Russia
And yet, after he recovered in Germany from the poisoning, he flew home.
As a #Russian politician, he could not contemplate the life of a political émigré, increasingly out of touch and irrelevant.
He said he had to be in Russia, whatever the risk.
But the risk was huge.'
