Hello and welcome to live coverage of opening practice for the Spanish Grand Prix!
07:47
We've had the first four flyaway races, now it's time for Formula 1 to race in Europe once more
07:48
The Circuit de Barcelona-Catalunya is one the teams know well, from year upon year of testing
07:48
It means this weekend should give us a good indication of the pecking order moving forward
07:49
Teams have also brought plenty of upgrades to the track, so there will be plenty to evaluate
07:49
For reference, Pirelli has brought its Medium (White) and Hard (Orange) compound tyres to Spain
07:49
There are also two DRS zones in place, as has become the norm
07:49
The first comes along the back straight, with the second following on the main straight

Remember, teams have an extra set for the opening 30 minutes

08:26
He steps out and pushes it clear with the marshals
08:27
Not the best start to the reigning World Champion's weekend
08:28
As Vettel's car is cleared away, track conditions return to green
