And not only that, but a music journalist, writing for urban music magazine Touch.
Umunna - MP for Streatham and Labour's Shadow Business Secretary - is standing as a back-to-Blairsics, nu-New Labour, business-friendly / pro-"aspiration" candidate.
Much of the story originally comes from a piece in The Independent from 2011:
Potentially the first hardcore continuum Prime Minister! He's got my vote, for sure.
(Although slightly alarmed by the detail in The Independent that he doesn't pronounce "garage" as "garridge" but "surprisingly he pronounces it the way you might expect the average MP to – with its second syllable rhyming with 'Farage', rather than, say, 'Beveridge'."
(Lovely touch that - Ukip versus the fellow who laid the groundwork for the Welfare State)
There is also some stuff from a DJ magazine interview by Carl Loben:
"I felt it was a bit of a shame that everybody got greedy, and it got too aggressive, the whole garage scene, which is why I slightly fell out of love with it. We allowed the MCs to take over, and it went from being quite a kind of happy, uplifting vibe to something that was a bit more aggressive — that I didn’t like"
That makes me reconsider my plans to vote for him, especially as not super sold on the Nu-NuLab, pro-enterpreneurial slant of his candidacy.
Although that will play probably well with the UKG generation I should imagine, now entering middle age and quite possibly feeling wistful about the flash-the-cash prosperous Britain days of the first Tony B prime ministership.
The mix-race Umunna certainly looks pure UKG, or should that be impure UKG - he's a photogenic blend of Nigerian, English and Irish, and was raised in South London, the son of a small businessman.
