Distant area Charlie goes over (5)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

A (area), FOOL (Charlie) reversed [goes over]. I wondered about the origin of ‘Charlie’ meaning a fool and discovered that it’s obscene CRS. Who knew? Yet it became an innocuous term used by many, presumably in total innocence. Now I need to know who Charlie Hunt was and what he did to deserve being commemorated in this way! ‘Berk’ is of similar origin, but I have long been aware of it, and its derivation is more obvious.
