Formula One champion Hamilton takes a knee

Hamilton, the sport's only Black driver, is an outspoken campaigner against racial injustice and for greater diversity.

He wore a black T-shirt with 'Black Lives Matter' on the front and 'End Racism' on the back - and appeared to be the only driver with Black Lives Matter on his shirt.

Television images showed six drivers standing behind those kneeling, including Red Bull's Max Verstappen and Ferrari's Charles Leclerc.
