Hundreds assembled for a socially distanced Say No to Racism rally in Glasgows George Square, where earlier this week members of the far right attacked a refugee-rights gathering. Hundreds of thousands of people have held mostly peaceful anti-racism protests across Britain since the death of George Floyd in Minneapolis on May 25, urging the U.K. to confront its own history of imperialism and racial inequality. Hundreds of far-right activists clashed June 13 with police near the Churchill statue in London, which had been boarded up for protection.
