A very nice hack by Stefan Magdalinski, which cross-references BBC News stories against the Wikipedia and, also blog entries on the subject matter retrieved from Technorati.
For instance, viewing this story on the happy news that Michael Howard is not thought to be prime-ministerial-material, returns wikipedia entries on Michael Howard, Tony Blair, the Conservative party*, the Liberal Democrats*, and the BBC!
A great proof of concept, which although BBC News have recently introduced their pretty good ‘google-news’-like Newstracker to some of their pages, introducing clearly-delineated links to blogs and the wikipedia would be far more engaging I believe.
(* the links go to ‘disambiguation pages’ due to there being multiple political parties by these names around the globe)
UPDATE: Stefan exposes the thinking/ideology behind the hack, and it’s source-code here
