MOSCOW (Reuters) -WhatsApp should prepare to leave the Russian market, a lawmaker who regulates the IT sector said on Friday, warning that the messaging app owned by Meta Platforms is very likely to be put on a list of restricted software.

Russian President Vladimir Putin last month signed a law authorising the development of a state-backed messaging app integrated with government services, as Moscow strives to reduce its dependence on platforms like WhatsApp and Telegram.

Anton Gorelkin, deputy head of the lower house of parliament's information technology committee, said in a statement on Telegram that the state-backed app could gain more market share if WhatsApp leaves.

"It's time for WhatsApp to prepare to leave the Russian market," Gorelkin said, noting that Meta is designated as an extremist organisation in Russia.

The company's Facebook and Instagram social media platforms have been banned in Russia since 2022 when Moscow sent tens of thousands of troops into Ukraine.

Meta did not immediately respond to a request for comment.

Russia has long sought to establish what it calls digital sovereignty by promoting home-grown services. Its push to replace foreign tech platforms became more urgent as some Western companies pulled out of the Russian market after 2022.

The Kremlin this week published a list of instructions from Putin, including an order to introduce additional restrictions on the use in Russia of software, including communication services, produced in so-called "unfriendly countries" that have imposed sanctions against Russia.

Putin gave a deadline of September 1. Gorelkin, referring to Putin's order, said WhatsApp was likely to be among those communication services restricted.
