The final test of the 2011 Formula One pre-season in Barcelona has been delayed until March 9.

8828 - Barcelona test delayed by 24 hours

Bahrain, which had been scheduled to host the opening grand prix of the year, was initially pencilled in as the home of the final testing session. However, due to political unrest, the Sakhir event was withdrawn at the start of the week.

As a result, all teams will complete their preparations in Barcelona, with original testing dates set for March 8 to March 11.

Those dates will now be put back by 24 hours, meaning testing will take place between March 9 and March 12.

The F1 season officially commences on March 25, beginning with the Australian Grand Prix.
