Sputnik said on Friday that the Russian-British media agency halt operations in Moscow and Washington and move its English language service to Russia and Washington, the group that launched it in 2014, said on Friday at a time when Russian-British relations had hit a low point.
Rossiya Segodnya said the move was part of a plan to reorganize its international presence in a more effective manner.
It was announced that Sputnik, which has offices in London and Edinburgh, would continue to cover British news.
Rossiya Segodnya and Sputnik did not immediately respond to requests for comment.
In 2018, the relations between London and Moscow hit a post-Cold War low when Britain blamed Russia for trying to kill the former double agent Sergei Skripal with a Soviet-developed nerve agent on British soil. Britain also denied Russia was to blame; Russia also accused Russia last year of trying to interfere in their 2019 national election.
In 2019 Russia warned British media operating on its territory that they should be prepared for consequences after Britain's media regulator fined the state-financed RT television channel for its coverage of Skripal's poisoning.
