Check out this other page:
http://commentisfree.guardian.co.uk/inayat_bunglawala/
Same format as the one linked at powerline, and it has this additional information:
"Inayat Bunglawala is media secretary of the Muslim Council of Britain."
So he's not an employee but a "guest commentator" of sorts.
There's all sorts of stuff on the web about him.
I didn't see his email address there. Anyone find it yet?
