Welcome to LIVE coverage of the Spanish GP from Barcelona! The race starts at 1pm UK time.

Grosjean takes fourth, then Kobayashi and Vettel. Despite starting from the back of the grid, Lewis Hamilton beats Jenson Button. They are eighth and ninth.

PASTOR MALDONADO WINS!! Incredible joy for Williams! Only Frank Williams keeps his cool! Alonso second, Raikkonen third.

Final lap! We are seconds away from an incredible result!

Maldonado's lead is up to 3.3 seconds - it's his to lose now, surely. What a moment for Williams and for Venezuela!

Sebastian Vettel is past Rosberg and into sixth place.

Alonso is losing grip, and it looks like Pastor Maldonado is going to hang on and win this race. Kimi Raikkonen is 9.0 seconds back.

It's now a 2.3 second gap between Maldonado and Alonso - has he broken the Ferrari man?

I tell you what, that Chelsea crest on the front of the Sauber is very distracting. Still, if you want to come sixth...

Over the line again, and what happened on that lap? Maldonado is 1.4 seconds clear! Raikkonen continues to close but remains 12 seconds adrift with seven laps to go.

Ferrari talk to Alonso over the radio, giving him permission to gun the engine to its maximum 18,000 revs. Vroom. Raikkonen is catching at 1.5 seconds/lap!

Down the start-finish straight again, and still Alonso is at bay. Raikkonen just 14.8 seconds back and he could be a real contender based on pit stops.

Maldonado eight tenths ahead as they cross the line... Alonso not close enough to make a move, though the DRS down the straight helped him close the gap.

Alonso is back in the DRS zone, 0.9 seconds behind Maldonado.

Raikkonen is 17 seconds off the lead, and in touch only if the leading cars both pit and he does not. Even then, it's a very long shot.

You have to imagine, if this were old school Ferrari, they might have made Maldonado's life a bit more difficult when he tried to lap Massa. Suppose you can't really do that sort of thing any more.

Maldonado noses his way past Massa and extends his lead to over a second, so no DRS for Alonso. Nice work from the Williams man.

Sky's Ted Kravitz reports that Williams do not intend to pit Maldonado again! This is all set for a fascinating finish.

Alonso is well within the DRS zone, as Raikkonen posts a fastest lap of 1:26.938.

Alonso has a go at Maldonado at turn one, but can't edge in front. He is all over the Venezuelan, though.

Raikkonen has just pitted, and there is just a tiny chance that if he can eke his tyres out until the end he could nick this.
