Placards stand fixed to the railings of the Parliamentary Estate at Parliament Square as Black Lives Matter activists, gathered for the second consecutive day of mass protest against racism, demonstrate on Whitehall in London, England, on June 7, 2020. Today marked the fourth massive Black Lives Matter protest in London in eight days, amid a global wave of anti-racism demonstrations sparked by the killing in police custody of a black man, George Floyd, in the US city of Minneapolis on May 25.
