Hello and welcome to the second free practice seesion for the Spanish Grand Prix - we're ten minutes or so away from the start

Join us again on Saturday for the third practice session - we'll have LIVE coverage from 10am (UK time)

So that's it, Red Bull's Sebastian Vettel claims the fastest time in the second free practice session with 1.22.808s. Ferrari's Fernado Alonso is second with Red Bull's Mark Webber third. Kimi Raikonnen finishes fourth, Felipe Massa fifth and Lewis Hamilton sixth. Marussia's Max Chilton brings up the rear with a time of 1.26.968s

Bar something ridiculous in the final few minutes, it looks like Red Bull will have two of the top three places with Ferrari's Fernando Alonso splitting Vettel and Webber

It's all gone a bit quiet - no-one really threatening at this stage and a few more tyres being changed...

Di Resta's car being pushed back up the pit-lane - a fair bit of tyre debris strewn across the track though....

Tyre failure for Paul Di Resta - he's pulled off to the side of the track and his left rear tyre looks knackered

20 minutes remaining - still no change amongst the top six - Vettel leads the way from Alonso with Webber in third

No rain so far, but the wind is certainly getting up

Webber about to start his twelfth lap with the same set of tyres .....interesting

Ferrari say that both Alonso and Massa re on medium tyres

Half an hour or so remaining - can anyone break in to the top six - they've been there most of this session so far.....

Vettel completes his next lap and the German posts 1m29.685s, while Webber is two-tenths slower with 1m29.881s.

Quick update on the times.... 1. Vettel 1.22.808s 2. Alonso 1.22.825s 3. Webber 1.22.891

Raikonnen up to fourth, less than a quarter of a second down on Vettel

Paul Di Resta up to ninth, Button slips to twelfth

Alonso goes second, but might have been better if he hadn't been held up by Sutil

As its stands, in order, we have Vettel, Webber, Alonso, Massa, Rosberg and Hamilton

Now Vettel storms to the front in 1m22.808s.

McLaren's Button and Perez finally go in to the pits - they've done 22 laps between them as McLaren warn there are no easy solutions to their heavily revised car

Webber pits and decides not to go for a second attempt
