Ismail has been a speaker at the corner [by his own account] for 20 years, is there pretty much every weekend when he's in London, and only engages in political/social debate.

I have had the devils own time getting a decent pic of him as he stands 99% of the time with his back to the light. ironically, this treatment captures more of his essence [my experience of him ;-)] than i've been able to do with a regular pic.
