11:58 Late lap from Hamilton as he heads out new supersofts. Will he actually do a lap?
11:57 Rosberg is slower than Verstappen in the first sector by a tenth, he is 0.073 down in the second and he pits... instead of finishing the lap off the German pits. He's not stopping, going straight through to practice a start.

11:36 Top ten: Ricciardo, Hamilton, Rosberg, Vettel, Raikkonen, Bottas, Massa, Verstappen, Perez and Gutierrez. Tyres: supersoft, soft, soft, supersoft, supersoft, supersoft, supersoft, medium, soft and supersoft.

11:19 The Manor driver has spun into the gravel and is told to "turn the car off" as he is well and truly beached. He wants to be pushed out by the two mechanics are hand are not getting it anywhere. Make that four mechanics and a digger.
11:18 Wehrlein off and red flag out!
11:17 Raikkonen is out on the supersofts but he is by no means setting the stage alight. He does a 1:38.5 which puts him P1 by only by 0.461s ahead of Verstappen, who was on the medium tyres.
11:15 Problems for Sainz as he has a puncture "rear right" and is limping his way back to the pits.
11:14 Hulkenberg is out but expect him to head straight back into the reports as he reports that the "lid" is open. And yip, the full flap is open.
11:13 Perez on the soft tyres does a 1:39.559. That splits the Bulls.
11:12 Sergio Perez, Kvyat, Pascal Wehrlein and Sainz are all out on track and straight into the action.

10:49 Breaking news this hour is that Toro Rosso have confirmed that Daniil Kvyat will partner Carlos Sainz next season. That puts an end to rumours about the Russian driver's pending axing or move to Force India.
10:42 While Red Bull and Ferrari are fighting over the 'best of the rest' title, Mercedes have already wrapped up the Constructors'. And with Ricciardo 101 points behind Rosberg, a Mercedes driver is guaranteed to win the Drivers' title. At present the odds are in Rosberg's favour as he is 33 points ahead of Hamilton.
10:36 Mercedes traded P1s in Friday's practices with Lewis Hamilton quickest in FP1 and Nico Rosberg setting the pace in FP2. Hamilton blamed "dangerous" brakes for his third-place time as he was also slower than Daniel Ricciardo. Sebastian Vettel was fourth.

15:22 The track tempreture is quite warm so that could be a reason as to why the supersofts are wearing out so quickly.
15:17 Supersofts don't seem to be lasting too long throughout the grid it seems.
