I really enjoy snooping around itunes for informative podcasts.
I found this episode which was published in October 2009.
It's about 30 minutes long and packed with information.

Episode 33: The African Diaspora in Britain
Marika Sherwood (senior research fellow, Institute of Commonwealth Studies, London) on the history of the African diaspora in Britain. She discusses aspects of her 2007 book After Abolition: Britain and the Slave Trade Since 1807, the 1945 Pan Africanist Congress in Manchester, and Pan-African biographies. Sherwood concludes by noting the inadequate treatment of black history in the UK school curriculum.
