Lewis Hamilton has become Britain's most successful F1 driver after winning his fourth world championship.
Hamilton secured his fourth title at the Mexican GP with the feat taking him clear of three-time world champion Sir Jackie Stewart on the roll-call of British F1 champions.
Hamilton's fourth championship also makes him only the fifth driver in Formula 1 history to reach the landmark.
Hamilton broke F1's all-time record for most positions earlier in the season and only Michael Schumacher has secured more race wins than the Mercedes driver.
What's being said about Hamilton's claim to greatness?
Mercedes boss Toto Wolff: "Lewis is about to break all records that have been set in Formula One, and it is just a matter of time that people will say he is on track to being the best driver that has ever existed."
Two-time world champion Fernando Alonso: "In a way I am happy that Lewis gets this fourth title. It's strange to see four Vettel and three for Hamilton, now there is much more logic. I think Lewis has had a better racing career."
Williams driver Felipe Massa: "Lewis is definitely one of the best drivers in the history of Formula 1. You cannot really take him away or in a different level compared to Michael Schumacher and Ayrton Senna. He's there."

Max takes win, Lewis takes championship
Former McLaren team-mate and 2009 champion Jenson Button: "He's probably the most gifted driver that's ever driven a Formula 1 car."
Force India driver Sergio Perez: "Lewis is the best driver on the grid. Lewis is something special."
Mercedes technical chief James Allison: "Lewis is right at the apex of his career and one of the all-time greats in this sport. To be alongside him while he gets his fourth championship in an extraordinary season of ebbs and flows and high drama is just brilliant for all of us."
Williams chief technical officer Paddy Lowe: "I worked with him from 2007 until 2016, so this is the only year l haven't worked with him and I only observe from a distance, but it looks to me like the best season he has ever driven."
