Russia is set to remain on the F1 calendar for the best part of the next decade.
We reported recently that Sochi race organisers have secured enough private sponsorship to pay the annual fee without any public funds.

And deputy Russian prime minister Dmitry Kozak told Tass news agency: "Negotiations were conducted and the contract for the formula one race in Russia was extended until 2025."
