Good morning and welcome to the third free practice session in Valencia, where we are underway.

Join us LIVE for qualifying which gets underway in just two short hours at 13:00 BST (14:00 CET).

And Button's time holds strong. He is fastest in the third practice session.

Alonso and Ferrari haven't had the best of sessions either. The Spaniard comes in 12th. Grosjean finishes in second for now.

But he's struggling on his final lap, poor timing amidst the traffic leading to cold tyres on Turn 2.

Vettel is in the midst of a late attempt to leap to the top of the times. A benchmark time with a single softs effort may influence how the team manages Q3.

Hulkenberg moves one-tenth clear of stable mate di Resta to go fourth. Schumacher up to seventh, Massa manages ninth.

Vettel and Webber are the only two drivers in the garage. The former will come out for a final push on softs but it looks like Webber's FP3 is over.

Button storms top of the pile with 1:38.562, narrowly faster than Grosjean's template.

Alonso locks up heavily going into Turn 12. Di Resta moves into third with 1:38.967.

The Ferraris, Hulkenberg, di Resta and Vergne are all back out too.

Rosberg is weaving around the back of the circuit to generate heat for an attack at the times.

The track is gaining traffic now as pace-setter Grosjean comes out for another crack on soft tyres.

Both Saubers, now fifth and sixth, are warming up for their run on softs.

And he moves just behind his team-mate Grosjean by a tenth of a second with 1:38'759.

Out comes Raikkonen, down to ninth as it stands, on his softs in the Lotus.

Rosberg returns on medium compounds to bring the current on-track driver count to just three with teams preparing for soft tyre action.

Things about to pick up as the onslaught of soft tyre runs looms.

Kobayashi springs into fourth with 1:39.562, ahead of team-mate Perez in fifth.

Remember that about minor works on the Red Bull? Scratch that. Webber is out of FP3 barring a miracle. He has left the car as work continues. It's not looking good.

Senna gets the hang of his softs run after traffic the first time around and moves into third on 1:39.543.
