Lewis Hamilton has committed his Formula One future to Mercedes by signing a new two-year deal.

The contract extension, announced ahead of Sunday's Austrian Grand Prix, will see Hamilton, 36, remain with the Silver Arrows until at least the end of 2023.

Hamilton's new deal is understood to be worth £40m a year.

The British driver, who trails Max Verstappen by 18 points in his bid for a record-breaking eighth world title, moved to Mercedes in 2013.

He said: "It is hard to believe it's been nearly nine years working with this incredible team and I'm excited we're going to continue our partnership for two more years.

"We've accomplished so much together but we still have a lot to achieve, both on and off the track.

"I'm incredibly proud and grateful of how Mercedes has supported me in my drive to improve diversity and equality in our sport.

"They have held themselves accountable and made important strides in creating a more diverse team and inclusive environment."
