Street of Shame - about the British newspaper industry (it used to be known as, as some still refer to it as "Fleet Street", but almost all the newspapers have moved elsewhere)
Rotten Boroughs - about local government
Signal Failures - about the railways
Other areas of British life are covered elsewhere in the magazine. But is also a satirical and cartoon magazine (the UK equivalent of "The Onion" - though probably a bit more 'grown up').
My daughter and son in law have given me annual subscriptions as Christmas presents for the last few years. A very good present, which keeps on giving! An online version is available at http://www.private-eye.co.uk/. I recommend taking a look (but be discreet, not in front of anyone who may be offended!)
