The original WhatDoTheyKnow code was written primarily by Francis Irving while working for mySociety.
In April 2007, Cabinet Office Minister Hilary Armstrong commissioned Ed Mayo and MySociety director Tom Steinberg to draft a "Power of Information Review" on how the government could serve the public's information needs better.
WhatDoTheyKnow.com is a website run by the registered charity UK Citizens Online Democracy (under the MySociety brand) which provides an integrated service for making UK Freedom of Information request in public.
