Nigel Moss: Can't believe Merc sent Hamilton back out on primes when he could have finished race on options and taken the race back to Rosberg!

Travis: Mercedes have turned boring. It’s like when Bahrain happened they never wanted it to happen again. Disappointing.

Rubens Barrichello has actually gone into a shop, seen a shirt with a tuxedo printed on it and thought: "You know what? That's pretty snazzy."

No Rubens. No.

Jenson Button refuses to be Verstappened. 

The McLaren and the Toro Rosso of Max Verstappen are racing side-by-side, almost touching, before Verstappen runs wide and rejoins ahead of Button. Surely he will have to give that position up? Or did Button run him wide?

Lewis Hamilton is charging and the gap is now 10.5s. His last lap is indeed a second faster than Nico Rosberg's. Can he keep it up to the finish? Tough, very tough.

Daniil Kvyat has clearly run over one of those little squares in Maro Kart that give you a random in-race perk. 

He is told over team radio that he has a power boost, and has one chance to use it. He's eighth, 1.6s behind Nico Hulkenberg.

Jack of all trades: if @LewisHamilton, external had pitted right after nico he would have challenged and overtaken him, now its impossible.

Mike Bird: Primes? Has Hamilton just blown it?

Alex Withington: I don't understand why Mercedes didn't put Lewis on super softs... only 13 laps to go.

To stop is the decision as Lewis Hamilton heads in. He takes on fresh soft tyres - matching Nico Rosberg's strategy and is back out in second and 13s behind his team-mate, with 12 laps to go. He's going to have to go more than a second a lap faster than his team-mate. Gonna be tough!

Lewis Hamilton: "If I was to back off and look after these tyres to end, how slow could we go?"

Mercedes engineer: "Lewis, it wouldn't work."

Hamilton: "Give me the calculation, guys."

Lewis Hamilton wants to go to the end of this race on his rapidly wearing tyres. He's warned off that idea, though. What will he do?

Sebastian Vettel stops and swaps for super soft tyres. He is back out and flying.

Sean Harrison: Are we actually witnessing Mercedes letting their drivers race & try different strategies?

Joe Lee: Nothing wrong with McLaren's part of the car but the Honda power unit is a joke. 

1) Hamilton 2) Rosberg 3) Raikkonen 4) Perez 5) Ricciardo 6) Vettel 7) Grosjean 8) Hulkenberg 9) Kvyat 10) Massa

This is being set up for a right old fight towards the end of the race. Nico Rosberg is gaining on Lewis Hamilton, the gap now down to 14s, but Hamilton is on tyres that are 27 laps old.

He's still going but you'd expect him to surely stop soon and switch to supersofts. If the Briton is going to win this, he will have to overtake Rosberg in the closing stages. Tense.

Lewis Hamilton: "What tyre is the other car [Rosberg's] on at the moment?"

Mercedes engineer: "The other car is on prime at the moment."

"Nico, if you can just pick the pace up a little bit, we need to close that gap," is the message over the team radio.

The German is currently 17s behind Lewis Hamilton, who is pushing hard to try and build up a big advantage ahead of his next stop.

Elsewhere, Daniil Kvyat looks to be eyeing a move on Nico Hulkenberg. Just half a second separates the two.

Mercedes are evidently happy with the lap times Lewis Hamilton is producing, but Nico Rosberg is lapping 0.6s faster. How long before the Briton is called in?
