Lewis Hamilton was the King of the Sochi Autodrom this weekend, the 2008 world champion looking like this track was made for him from first practice to today's race in what was a difficult weekend for Formula 1 as thoughts remained with Jules Bianchi, who is in hospital with severe head injuries following a crash at Suzuka last weekend.

Hamilton now leads the championship by 17 points with three races and 100 points remaining, courtesy of double points at the last race in Abu Dhabi.

We've got a three-week gap until the next race, with Austin playing host to the United States Grand Prix. I'll be back at 15:30 BST on Friday, 31 October to bring you live coverage of first practice. Until then, it's good afternoon from me.

So Lewis Hamilton leads the way in the drivers' standings with Nico Rosberg and Daniel Ricciardo second and third respectively. Valtteri Bottas moves up to fourth, with Sebastian Vettel dropping to fifth. You can see the full standings here.

Jenson Button, who has yet to sign a deal for next year, is asked what he would like to be doing next season: "I'd love to go racing and be in a competitive car in F1 and that is what I am doing everything to do.

"It was tough [not knowing what McLaren were doing] for a little while but it's not tough any more, it's tougher for my team mate. I have been in the sport for a long time, I have won a world title and won 15 races but for Kevin [Magnussen] he is in his first season and there is more pressure on him to get a drive. I just hope they make the right decision."

"I was in a battle with Lewis and I messed up," says Nico Rosberg. "I was a bad mistake too. It was my corner - or I thought it was - but it was the first time arriving there at full speed with full fuel. I thought I wouldn't get into the top 10 after that but the car was amazing.

"There was one phase when I had a lot of degradation. I got a lot of oversteer and I thought they wouldn't make it to the end of race. I was nursing them a lot. In the end I could have got more out of them. I was driving the whole race on tyres that they said you cannot do any more than 29 laps on them."

Looking ahead to the last three races, Rosberg adds: "I need to continue to attack and I need to look to win them. All the next three races are my favourites."

"It was important that we show everything we can for Jules and his family," says Williams' Felipe Massa, who finished 11th. "I am a very big friend of his so it is not easy for me to talk about it but it was good to see all the drivers come together for him. We are all together all the time but we really showed it today."

"It's great that [Valtteri] Bottas did such a good job for us today but Mercedes were just too fast for us," says Williams deputy team principal Claire Williams. "Big congratulations to them because they have obviously taken the constructors' title.

"When you see Nico come in that early you think it's a shoe-in and then maybe something will happen to Lewis and we can get on the top step but as Valtteri said third place was really the best we could expect.

"We have got a great car it's just a shame Felipe [Massa] couldn't make it past [Sergio] Perez but hopefully he can score some more points in Austin but the big thing today was that we have extended our lead over Ferrari."

"We really went in to the race thinking that we could battle with Mercedes for the win but that was not the case in the end," says Williams' Valtteri Bottas, who starts third. "We are not here to be the best of the rest we are here to be the best and we are aiming for that.

"There are three races to and it's going to be really hard to beat them in those races but over the winter we will be working to close that gap."

"There is an incredible synergy within the team, there is huge support from the team and they are real racers," says Lewis Hamilton. "They really want to win and this car and this engine are just mind-blowing.

"I am very happy here and I am very committed as they are with me," says Hamilton, whose contract runs until the end of 2016. "Lets get this season out of the way and then we will talk about a new contract.

"I think longevity with a team is something really special, I had six great years at McLaren and I would love that here with Mercedes."

"We will all celebrate together and then prepare for the rest of the races, there are still three very tough races to go," adds Lewis Hamilton, who leads Nico Rosberg by 17 points with 100 still on the table.

"I have never won in Brazil so I am really looking forward to that. Nothing changes, we still have to attack. Nico is driving phenomenally well and I still have to compete with him."

"The circuit is just great and it's great fun to drive, OK I wasn't being pressured during the race but when you lead there is a different kind of pressure," adds race winner Lewis Hamilton.

On the battle into the first corner with his team-mate, Hamilton says: "The last time we [Nico Rosberg and I] were that close the guy took me out. I was just making sure I didn't get any punctures and got round the first lap.

"I still thought he would be pushing me but he did the damage to his tyres but I was so surprised he finished second on the same tyres though."

"It's been an incredible weekend and it's been an unbelievable job from this team for what they have achieved and it's been great to be a part of it," Lewis Hamilton tells Suzi Perry. "The car has been a dream to drive and I could have only dreamed of a day like this."

Lewis Hamilton heads round the garage hugging mechanics before heading back out into the pit lane to speak to Suzi, Eddie and David.

Lewis Hamilton and Nico Rosberg join Niki Lauda, Toto Wolff and Paddy Lowe at the front for the celebratory team photo. They pose with a pit board which reads "17 BIA" in tribute to Jules Bianchi, who is in hospital with severe head injuries following a crash at last Sunday's Japanese Grand Prix. They then swap it for a board which reads: "2014 World constructors' champions".

If you missed the start of the race, watch a dramatic lock-up from Nico Rosberg, which saw the German briefly take the lead before having to hand the place back to Lewis Hamilton and then stop for fresh boots at the end of the lap.

"I think the start - we knew that was the only chance for us to have some joy today," says Ferrari's Fernando Alonso, which finished sixth. "We attacked and gained some positions but we were the fourth fastest [team] on the track today so we didn't have the pace to keep Kevin [Magnussen] behind. So it was no big change for us and sixth is what we deserved today."

"We all raced for Jules today - it's not a complete race because we were missing one of our colleagues. And in the next three weeks we hope to be able to stand in front of your cameras and have some good news for you."

Is there any news about Jenson Button's future at McLaren? "No," says Eric Boullier. Well that's definitive.

"Nothing related to us, maybe a personal issue," says McLaren racing director Eric Boullier when asked about why Jenson Button appears downbeat. "He's doing very well. His pace at the end of the race was very good."
