A review by the UK Office of Public Sector Information in 2009, reported in an article in CreativeCommons.org, Public (UK) perception of copyright, public sector information, and CC, found that,

More background about the move is covered in Personal Computer World's article Crown Copyright switches to Creative Commons.
