SINGER Kelis has accused Britain of being "racially decades behind progression" after she was allegedly subjected to abuse at an airport because of her skin colour.
Using her Twitter account, the American musician claimed she was accused of queue-jumping by a "red- faced sweaty man" who called her a "slave" and "probably a disgusting Nigerian" and told her to call him "Sir".
Kelis (32) said that man labelled her "Kunta Kinte" -- the name of a slave in Alex Haley's book Roots -- and "ranted and raved some more".
She claimed an official behind the passport desk had laughed, shaken his head and said "Kunta Kinte".
The musician, who did not name the airport, said she did not lose her temper as she was travelling with her two-year-old son.
The incident apparently took place as Kelis was travelling home after performing at Bestival on the Isle of Wight. Kelis, whose hits include Milkshake and Caught Out There, tweeted: "I didn't say anything at the time of the riots in London for a lot of reasons. But I am in London all the time and today I'm gonna say that the racial issues in the UK are disgusting.
"It's racially decades behind progression because everything is swept under the rug. People don't talk about it. People don't fight about it."
The UK Border Agency was unavailable for comment.
