There is a story running on the BBC news site about William Shatner apologising for something he said on Have I Got News For You about prostitutes in Cornwall. What I like about this story is the Related Stories section:

Cornish Anger

I like to think this is just a small selection of the BBC news' Cornwall archive:

Anger at Cornish 'befuddlement' fun-making
Anger at Cornish 'hang around tin mines' observation
Anger at Cornish 'lost in a supermarket' laughter
Anger at Cornish 'one sardine short of a shoal' comment
