Google and Apple have removed an election app from Russian opposition leader Alexei Navalny from their app stores, the politician's team announced on Friday.

The US should not interfere in domestic affairs in Russia, according to the companies.

Russia will vote for a new parliament on Friday.

Putin's party, United Russia, is expected to win.

Allies of Navalny, fiercely opposed to Putin's party, planned to use the deleted app to campaign against the incumbent president.

Earlier this month, Russia demanded that Google and Apple remove the apps from their stores.

The country threatened fines for the tech companies.

Russia said it saw a refusal as US interference in the Russian parliamentary elections.

Apple and Google did not immediately respond to questions from

.

Why the companies removed the apps is therefore not fully known.

Navalny, 45, was sent to a penal camp earlier this year after returning from Germany.

He was treated there for poisoning with the substance novichok.

The United States and the European Union blame Russia for the poisoning.

Because of the treatment in Germany, Navalny violated the provisions of a previous suspended sentence he received.

The opposition leader is currently serving a 2.5-year prison sentence for fraud.
