Nico Rosberg extended his incredible winning streak to seven races with a comfortable lights-to-flag victory at the Russian Grand Prix.
Russian President Vladimir Putin arrived at the Sochi Autodrom racing street circuit, where Russia's stage of the Formula One World Championship is being held on Sunday.
Upon his arrival, the Russian leader was greeted and escorted by Formula One Group Chief Executive Bernie Ecclestone.
The Olympic city hosts the Grand Prix for the third time after Russia secured the right to annually hold the championship's stage from 2014 to 2020 on October 14, 2010.
Construction of the 5.848-kilometre, 55,000-capacity circuit came under the design supervision of renowned architect Hermann Tilke.
The track is integrated into the Olympic Park infrastructure, with facilities located in close vicinity to the Olympic Park railway station and to the roads which connect the Olympic venues with Sochi International Airport.
The track width varies from 13 metres at its narrowest point to 15 metres at the start-finish line. The circuit, which runs in a clockwise direction, consists of 12 right- and six left-hand corners, and combines both high-speed and technical sections. On their first visit to the track, Formula One cars reached 332 km/h on the 650-metre straight between the first and second turns
