Jenson Button will not start the Bahrain Grand Prix after McLaren failed to resolve electrical issues on his car.

The 2009 world champion has been beset by problems throughout the Bahrain weekend, stopping on track in three out of the four sessions and failing to set a time in qualifying. While the McLaren was permitted to start from the back of the grid, it remained in the garage as the grid formed.

McLaren confirmed the team worked overnight to try and get the MP4-30 ready to race but when the car was fired up it still showed signs of the electrical problems which have hampered Button since Friday. With the problem causing the car to shut down on track, the team opted not to race due to the high probability of the issue happening again.

McLaren and Honda will now investigate the problem to try and find the cause ahead of the Spanish Grand Prix, when a new spec engine will be introduced.

Button's failure to start is the second time a McLaren has not made it to the grid this season, with Kevin Magnussen suffering from a power unit problem and not starting the race in Australia.
