Michael Masi has been sacked as Formula 1 race director after the Abu Dhabi controversy which saw Lewis Hamilton lose the world title.
Masi's handling of the final laps of the race in Abu Dhabi has been under intense scrutiny since the decision which saw Max Verstappen claim a maiden world crown.
The race director failed to correctly apply the rules during a safety car period late in the race which had a direct impact on the fate of the championship.
