McLaren's car has been given the all-clear to race at the Bahrain Grand Prix after passing scrutineering checks on Thursday.
FIA technical chief Charlie Whiting checked the car's rear wing this morning and gave it the green light, despite rival Red Bull Racing having expressed doubts about its legality ahead of Bahrain.
Red Bull believed McLaren was making use of the air flow through the engine cover to deliver a straight-line speed advantage.
The FIA was originally scheduled to inspect the car before flying to Bahrain, but that had to be delayed until today.
The MP4-25, however, was given the all-clear by the FIA stewards ahead of tomorrow's practice sessions.
