Zanzibar-born artist Lubaina Himid has won the prestigious Turner Prize, awarded each year in the UK.
The 63-year-old Preston-based artist won the £25,000 ($33,500) prize for work addressing racial politics and the legacy of slavery.
She is the oldest winner and the first black woman to pick up the art award.
The judges praised her "uncompromising tackling of issues including colonial history and how racism persists today".
She told the BBC afterwards that her win probably wouldn't change people's perspectives and attitudes, but added: "I think it will get people talking, which is the point of my work."
As to what she will do with the money, she said:
I spend quite a lot of my money working with other artists, sometimes asking them to make things or helping them to make things when maybe they didn't get a grant or whatever.
So I'll do a bit of that. And I'll buy some shoes."
Himid moved to the UK with her mother not long after her birth in Zanzibar in 1954 - 10 years before the archipelago became part of Tanzania.
In January she told the UK Guardian newspaper: “I think I was always trying to paint Zanzibar somehow. I was always trying to live it in my head.”
