I think I've posted stuff from Private Eye here before.
This is a recent article on the RSPCA.
Normally, I wouldn't be bothered about any copyrighting issues with posting pictures taken from a newspaper, but Private Eye are the good guys of journalism, so I think I ought to follow this with a recommendation to subscribe.
I'll try to remember to post any future stories they do on animal rights. They cover a lot of government and business stuff as well though, so it's well worth buying to read the whole magazine.
