Six-times Formula One world champion Lewis Hamilton donned an #EndSARS T-shirt protesting against police violence in Nigeria for a pre-race television interview at the Portuguese Grand Prix on Sunday in Portimao.

Thousands of Nigerians have been demonstrating for several days against a police unit, the Special Anti-Robbery Squad (SARS), which has now been disbanded.

Rights groups have for years accused the police unit of extortion, harassment, torture and murders.

“I’ve got to show this,” Hamilton, Formula One’s only Black driver, told Sky Sports television as he revealed a green T-shirt with #EndSARS written on it at the end of the off-grid interview. He said he did it to show solidarity with Nigerians.

Hamilton has continued to show a bit of activism using every opportunity in his sport.

The Briton reverted to his usual “Black Lives Matter” T-shirt for the officially-sanctioned pre-race anti-racism gesture on the starting grid.

Formula One’s governing body last month set out new pre- and post-race rules for driver attire.

This was after Hamilton wore a T-shirt on the Tuscan Grand Prix grid with the words “Arrest the cops who killed Breonna Taylor” on the front.

Taylor, a Black medical worker, was killed by police officers who burst into her apartment in Louisville, Kentucky, in March.

“Lots of rules have been written for me over the years and that hasn’t stopped me,” Hamilton said when the new rules were announced.
