Following Kelis' earlier rant about the dominance of racism in the UK, a spokesperson for the Runnymede Trust has opened out about the fact that the problem is just as bad in the US. 

The 'Acapella' singer took to social networking site Twitter to tell her fans that she was called a "slave" and "disgusting Nigerian" by a fellow passenger at a British airport, and also declared the UK "racially decades behind progression". 

A person from the Runnymede Trust, which is an independent race equality group, told WENN:

"It's worth noting that we're not a multi-racial paradise in the U.K. but there is a fight back here, and there are lots of ways in which musicians like Kelis can contribute to that. Things like the UpRise music festival in London - 10,000 people making it clear they are against racism."

"But I don't think we have got a huge amount to learn from America in terms of the racism that operates over there. We are struggling against racism in the same way as people are in the States. What's interesting about it is you can be a star and be really famous and still not escape some of the racism that exists in both the U.K. and the States."
