Kath Lissenden quotes a gem from the Mail -
"The Conservatives have deleted everything the party said before the last election from its website to stop people checking if they have broken promises. A decade of speeches, articles and press releases has been wiped from the archive, with the material also disappearing from search engine results. The attempt to rewrite digital history appears to be at odds with David Cameron’s pro-transparency declaration that political leaders had to ‘let go of the information that we've guarded so jealously’."
Yes, it's straight out of 1984. From Wikipedia -
"A memory hole is any mechanism for the alteration or disappearance of inconvenient or embarrassing documents, photographs, transcripts, or other records, such as from a web site or other archive, particularly as part of an attempt to give the impression that something never happened....Big Brother's Ministry of Truth systematically re-created all potential historical documents, —in effect; re-writing all of history to match the often-changing state propaganda. These changes were complete and undetectable."
Latest - looks like they're ALL doing it....except the LibDems.
