No 'regret' about return to Russia: Navalny

The Kremlin's most prominent critic Alexei Navalny said Monday he did not regret returning to Russia a year ago, despite his jailing and a historic crackdown on the opposition.

Navalny was detained in a Moscow airport on his return to Russia from Germany on 17 January last year, ushering in a months-long crackdown that has seen his most prominent allies imprisoned or exiled.

"I don't regret it for a second," Navalny wrote in a post on Instagram from a penal colony outside Moscow.

"Having served my first year in prison, I want to tell everyone exactly what I shouted to those gathered outside the court when a convoy led me to a police van: don't be afraid of anything," Navalny added.

"This is our country and we have no other." Navalny's August 2020 poisoning with the Soviet-designed nerve agent Novichok and his subsequent arrest sparked widespread condemnation abroad as well as sanctions from Western capitals.

Moscow has refused to open an investigation into the attempt on his life, claiming there is insufficient evidence to open a probe and blaming Berlin for not cooperating.

On his return to Russia Navalny was jailed for more than two years on old fraud charges he says are politically motivated.

Ahead of the anniversary of his arrest, Russia last week added two of the opposition leader's closest aides to a list of "terrorists and extremists".

Ivan Zhdanov, 33, led Navalny's Anti-Corruption Foundation, which produced hugely popular video probes accusing the authorities of systemic graft, while 41-year-old Leonid Volkov headed Navalny's network of regional offices.

Both of those organisations were banned by Russian courts and shuttered by staff fearing prosecution.

Last month, investigators questioned several former regional Navalny coordinators, including Ksenia Fadeyeva, who is also a local lawmaker in the Siberian city of Tomsk.

Allies say she is facing up to 12 years in prison for working with an extremist organisation.

Investigators last year launched a new extremism probe against Navalny that could see the opposition leader spend up to 10 more years in jail.

The European Parliament last year awarded Navalny the Sakharov Prize for Freedom of Thought after he was nominated, but passed over, for the Nobel Peace Prize.

Ramping up a historic crackdown on critical voices in Russia, authorities have designated dozens of rights groups, media outlets, journalists and anti-Kremlin figures "foreign agents".

In December, courts ordered the shutdown of the country's most prominent rights group, Memorial. The group chronicled Stalin-era purges and campaigned for the rights of political prisoners, migrants and other disadvantaged groups.

A court on Monday turned down two appeals Navalny had brought against authorities over his treatment in the penal colony. Navalny appeared in court via video link, sitting behind bars in a prison uniform before the Petushki district court in the Vladimir region where he is being held.

The cases heard on Monday concerned his prison salary and his designation as a flight risk, the independent Russian television channel Dozhd reported.
