Jenson Button gave the McLaren MP4-29 its first run today, completing a slow installation lap before returning to the garage.

The car didn’t run yesterday after the team struggled throughout the day with electrical problems.

Pirelli has nominated today as its wet tyre running day, and has used a tanker to wet the track, although there is also a light sprinkle of rain.
