12:32
That will have to be fixed when he returns to the pits

12:33
That's an improvement of around a second between compounds
12:37
The Mercedes and Ferrari drivers are all now on the Mediums

12:39
Rosberg takes P1 with a 1:25.973
12:39
Hamilton posts a 1:25.524 to comfortably reclaim the top spot
12:40
This is developing into a fascinating intra-team battle
12:40
Only time will tell if Rosberg has enough to respond later in the weekend
12:40
Amid those times, Alonso moved up to fourth

Some bodywork appears to have flown off Chilton's Marussia
12:55
It looks as though it's the 'monkey seat' from the rear of the car
12:55
The Briton, who was on his first Medium tyre run, returns to the pits
12:56
The yellow flags are out, presumably for the debris which has settled between Turns 15 and 16

13:08
He is working through a Medium tyre run at the moment
13:13
The ever-impressive Hamilton is keeping his growing stint in the 1m30s

From the television images in the media centre, we would agree
13:26

13:26
Vergne's right-rear wheel has come off
13:27
The Frenchman has stopped his car just before Turn 3
