F1 Russian Grand Prix build-up LIVE: Norris leads Hamilton in dramatic end to race as track slippery with rain

LEWIS HAMILTON has won a thrilling Russian Grand Prix in a crazy, rain-soaked finale.
The track had been dry for the best part of 48 laps but rain drenched the track in the last five laps.
Stubborn leader Lando Norris insisted on staying on the track, but his tyres could not handle the slippery tarmac.
Hamilton, who pitted for new tyres, took advantage and reeled his fellow Brit in in no time, as Norris slid off the track for an easy overtake for the champ.
And it resulted in 100 GRAND PRIX WINS for Hamilton, a stunning achievement in his trophy-laden career.
Max Verstappen did an outstanding job as well, coming from the back of the field to surge into second on the last lap, thanks in part to Norris' blunder.

STUCK ON 99
Lewis Hamilton is still waiting on his 100th win in Formula 1.
The seven-time world champions last won on July 18, taking the chequered flag at Silverstone.
But he is winless in the four GP's since then, although a 100th win will inevitably come at some point.
And he said: "It will definitely come, but of course I'm going to go all out to get number 100."
TOTO PREDICTS
Mercedes Team Principal Toto Wolff has predicted future Mercedes driver George Russell to lead in the early stages of the Sochi GP.
Russell qualified in third for Williams, and is set to link up with Lewis Hamilton and Mercedes next season.
And Wolff said: “It wouldn’t surprise me to see George in the lead after turn two, and it would also be fun to watch.
“If Lewis also manages to gain positions, we would have the present and the future of the team in the top two.”
TWO HOUR WARNING
There's just two hours to go now until lights out in Sochi!
Lando Norris will start in pole position - his career first - after holding off challenges from Carlos Sainz, George Russell and Lewis Hamilton.
Hamilton made a costly mistake and he hit the pit-lane wall during Q3 as he starts fourth on the grid.
MAX REACTS
Max Verstappen has revealed he needs thinks to go ‘a bit wrong at the front’ to land a podium finish with the Dutchman starting at the back of the grid in Sochi.
“I don’t know. It depends on the first lap, on things that happen in the race.
“Of course I try to score points but I need a bit of help with things going a bit wrong at the front, so let’s see.
“At the end of the day you need to do it on your own. Whatever happens in the front, anyway, I’m not involved in that.”
PATCHED UP
Lewis Hamilton's Mercedes has been repaired to 'full working order' ahead of lights out at 1pm.
Hamilton spun off the track in the final sector on his last lap, and his rear wing nudged the barriers.
But after the Mercedes team inspected his car overnight it's been confirmed there was no lasting damage.
BOTTAS AT THE BACK
Valteri Bottas will start today's race in 17th after Mercedes changed the power unit in his car for the second weekend in a row.
The Finnish driver originally qualified seventh for today's Sochi GP, but has now been moved to the back of the grid.
He will start ahead of Max Verstappen however, with the Dutchman chosing not to set a representative time during the qualifying session.
WANTS CHAOS
Red Bull's Max Verstappen has admitted he won't be driving carefully despite starting at the back of the grid this afternoon.
He told Motorsport.com: If you're careful, you won't get past anything.
"You do have to drive forward the way I think you should and then we'll see. It's also largely down to the start and the situation you're in at the time.
"You can't think too much about that beforehand, you have to do it yourself at that moment."
LATEST WEATHER
The Met Office are not predicting the same soaking wet day in Sochi that we saw yesterday.
Thunderstorms in Russia forced the final practice session to be qualified.
But despite there being a small chance of rain throughout the race, the rain could well stay away for the duration the drivers are on the track.
RACE DAY
The 15th race in the Formula One season gets underway today, with Lando Norris on pole in Sochi.
Carlos Sainz joins him on the front row, followed by George Russell and Lewis Hamilton.
It means three out of the first four drivers on the grid are from the UK.
Lights out for that one is at 1pm.
TURN TWO
Mercedes boss Toto Wolff has said it wouldn't be a surprise if future Merc driver George Russell is in the lead come turn two tomorrow.
Russell will start from P3 tomorrow, ahead of future team-mate Lewis Hamilton.
Wolff said: "It wouldn't surprise me to see George in the lead after Turn 2.
"It would be fun to watch as well.
"If Lewis manages to capture positions as well, we would have the present and the future of the team in the top-two at that point."
SAINZ SPEAKS
Carlos Sainz, who will be hot on Lando Norris' heels tomorrow, had his say ahead of tomorrow's race.
He said: "Right after Q2 I could see that the slicks [tyres] could come into play. I put in a pretty strong lap.
"This weekend we’ve been looking a bit stronger.
"We will put on a fight [in the race] and try to have some fun."
CLOSE CALL
Seb Vettel missed out on Q3 by the slimmest of margins.
P4
Lewis Hamilton will start tomorrow's Russian Grand Prix from P4.
HE'S LANDED
Lando Norris took his first ever Formula One pole position at the Russian GP after a nightmare session for Lewis Hamilton, writes GEORGE BOULTON.
The young Brit will start on the front row alongside Ferrari's Carlos Sainz with George Russell third on the grid for Williams.
Hamilton made a costly mistake as he hit the pit-lane wall during Q3 as he starts fourth on the grid.
Torrential rain eased in Sochi and as the session progressed the track dried out in the dying minutes of Q3.
As the field dived into the pits for dry tyres, Hamilton clipped the pit-lane wall putting himself and Mercedes on the back foot.
The mid-field pounced on his error as Norris, Sainz and Russell dramatically improved their times.
Hamilton was struggling to get heat into his tyres and as he pushed on his final lap, he spun out and bumped the barriers.
A dejected Hamilton said: "Twice in the wall... that's very rare for me.
"I'm really sorry to all the team because that's not what you expect from a champion."
TOP THREE! MCLAREN, FERRARI AND WILLIAMS
