If Parliament is to reflect the face of modern Britain there should be at least 50 Asian and Black MPs. But today only 2% are from an ethnic background - just 15 from a total of 646.
At the current rate of change it could take 75 years to get anywhere near a representative amount, so what are the chances of Britain ever getting its own Asian prime minister?
Ashok Viswanathan, from Operation Black Vote, said: "It's conceivable that we could have a prime minister who's African, Asian or Caribbean in the next 25 to 30 years."
But could this optimism become a reality?
Ali Miraj was 23 and a part-time DJ when he was elected as a Conservative councillor in Ruislip Manor, Hillingdon, north-west London.
This gave him the experience and the appetite to go further - so he went on to contest his first seat in Aberavon, south Wales, at the 2001 general election.
