Mikhail Khodorkovsky commented on his social media on Alexey’s Navalny’s arrest at Sheremetyevo airport:

The arrest of Navalny marks the transition of Putin’s regime to demonstrative repression, in the style of the Central Asian despots.
Politicians and companies that allow themselves to make excuses for this behavior are open enemies of democracy.
Such position will cost them dearly. All of us, who stand for the rule of law and the democratic future of Russia, must now take a stand in the general system to fight totalitarianism and lawlessness.”

Арест Алексея Навального знаменует переход путинского режима к демонстративным репрессиям в стилистике среднеазиатских деспотий.
Политики и компании, позволяющие себе оправдывать такое поведение, являются открытыми врагами демократии.
Подобная позиция будем им дорого стоить.=>

Commenting on the event for Reuters he added:

“Putin feels he has to show he is the main animal in the herd or … people will believe that he is no longer the top dog,”
