McLaren have ramped up security around their pit garage at Jerez following the last-minute deal that has got world champion Fernando Alonso into their car.
As negotiations continued late into the evening last night to try and secure Alonso's release from his Renault deal, McLaren mechanics were despatched to the track at 5am this morning to prepare the pits.
When it became clear that McLaren had got the green light, first revealed by autosport.com, the team swung into action to prepare an MP4-21 chassis for the Spaniard.
All sponsorship stickers were removed from the car and Alonso has been forced to use a plain white helmet, white overalls, with only a Spanish flag on the belt.
As well as an increased number of barriers around the back of the team garage, photographers have also been discouraged from taking photographs of Alonso when in the pits.
Despite the interest, Alonso got down to work swiftly with the team and completed his first installation lap just after 9am.
