Two Russian citizens have expressed their shame and fury following the death of Alexei Navalny.
Kremlin critic says three reasons behind timing of Navalny 'murder'
One of the many questions that surround Alexi Navalny's death is why it happened now, almost three years after he returned to Russia.
Author and financier Bill Browder said there were three reasons for the timing.
Firstly, Vladimir Putin wanted to eliminate a political opponent.
Secondly, he wanted to show Russians that if you oppose Mr Putin you will face death.
And thirdly, it sent a message to those sitting at the Munich Security Conference, where world leaders meet to discuss defence issues, that Mr Putin can "cross every red line and get away with it".
