Tyron Frampton of slowthai attends the Hyundai Mercury Prize: Albums of the Year at Eventim Apollo, Hammersmith on Sept. 19, 2019 in London.

The Mercury Prize award ceremony took place in London on Thursday night (Sept. 19), and rapper Slowthai made quite the political statement during his performance.

Nominated for his album, Nothing Great About Britain, he held up a a fake severed head of U.K. prime minister Boris Johnson, shouting "F--- Boris," and, fittingly, "there's nothing great about Britain."

Slowthai did not go home with the award, though. Rapper Dave, real name David Orobosa Omoregie, was given the honor for his debut album, Psychodrama, released back in March.

The Mercury Prize is awarded to the best UK album released by a British or Irish act, with a prize of £25,000.
