Sebastian Vettel does a 1:29.247 to go third, that's 0.455 seconds off the pace! Mercedes are looking like being in a league of their own.
Kimi Raikkonen goes P4 with a 1:29.684 with Max Verstappen fifth, Daniel Ricciardo sixth and Felipe Massa seventh.
No times yet from Romain Grosjean, Nico Hulkenberg or Jolyon Palmer.

... it's a 1:28.844 for Bottas, the fastest lap ever here!
Well, until Lewis Hamilton completes his lap. He does a 1:28.792 to move into provisional pole...

Daniel Ricciardo sets the pace with a 1:30.007 but that's already been well beaten today so he will be tumbling down the order.
Here comes Valtteri Bottas...

Tom Clarkson has just asked Fernando Alonso, (who unfortunately had a power unit failure in Q2), what animal he is going to be in the car tomorrow.
"Errm it has to be an animal from here so maybe a quick camel!"....

Daniel Ricciardo and Max Verstappen are the first two to head back onto the track. Their rivals are not far behind, though.

BBC Radio 5 live Formula 1 analystWe have a battle royal between the silver arrows and the prancing horses!
Ferrari have really stepped up their game here. I have to say though, Lewis Hamilton has such an edge.

So will Lewis Hamilton secure a seventh successive pole position? There was just 0.061s between the top three at the end of Q2. So tight.
The shootout for the top 10 is under way.

Wow!
Jolyon Palmer does a 1:30.899 to go 10th while Nico Hulkenberg leaps up to fifth with his lap - a 1:30.169.
That's both Renaults into the top 10 shootout, the first that has happened since Belgium 2015.

... Lance Stroll is up to 10th... but it is not enough as Romain Grosjean immediately pushes him down to 11th as the Haas does 1:30.857 to go eighth.
