Nico Rosberg has ended speculation about his immediate F1 future by penning a new deal with Mercedes for the 2017 and 2018 season.

The German, who currently leads the 2016 Formula 1 World Championship standings by a single point from team-mate Lewis Hamilton, joined Mercedes in 2010 when the German firm entered the sport as a constructor and has gone on to win 19 races with the Silver Arrows.

Runner-up to Hamilton in 2014 and 2015, Rosberg's new deal will see him remain with Mercedes until the end of the 2018 season, bringing him into line with the conclusion of Hamilton's current contract.

"We are delighted to announce that the Mercedes AMG Petronas Formula 1 Team has signed a two-year contract extension with Nico Rosberg for the 2017 and 2018 Formula One seasons," read a short statement from the team.

"Nico has been a core member of the Silver Arrows since the team returned to the sport in 2010 and has played a crucial role in the team's success in that time."

Rosberg's deal comes after weeks of speculation over his future within the Mercedes fold. Indeed, though Rosberg had repeatedly expressed a desire to stay at Mercedes, paddock rumours suggested he wasn't satisfied with the terms being presented.

Nonetheless, the deal now extends his stay at Mercedes for what will be nine seasons when his contract comes to an end.

As of the 2016 British Grand Prix, Rosberg - who made his F1 debut in 2006 with Williams - has achieved 19 wins, 25 pole positions and 47 podiums, with all but two rostrums coming at Mercedes.
