There is a three part documentary series called "Lefties" starting tonight on BBC4 TV tonight at 9pm. The first external link on this page
http://www.bbc.co.uk/bbcfour/documentaries/features/lefties.shtml
is to
http://en.wikipedia.org/wiki/Left-wing_politics
Nice to have a link to Wikipedia - but it would nicer still if the article was cleaned up today (or the cleanup notice removed?).
You could also question why the web producer at the BBC chose that particular link.
