John Davidson, who has Tourette’s, could be heard shouting as Sinners stars Michael B Jordan and Delroy Lindo presented an award.

Mosaku was speaking on the red carpet of the Actor Awards in Los Angeles on Sunday and said she is not sure if she can forgive the BBC.

The Tourette Syndrome campaigner told US magazine Variety that he remembers a microphone was placed in front of him at the awards ceremony.

It is understood Warner Bros requested the incident be removed from the broadcast.

The campaigner could be heard shouting a racial slur during the ceremony.
