Will there ever be a UK equivalent of Barack Obama?

The UK is a far more progressive nation than the US. We’ve just recently seen a woman as serious candidate for the US presidency for the first time, while thirty years ago Great Britain put a woman in the prime minister position. Now we are on the verge of having (knock on wood) the first African-American president of the United States or America. With the UK black population just over 2% (as opposed to 13.4% in the US), is race an issue in British politics? Is there an up and coming black British up and political figure in England? Is there a near future where the UK could find itself with a black prime minister? I’m especially anxious to read what you British flutherers have to answer.
