Letters sent by Prince Charles to government ministers during 2004 and 2005—the so-called black spider memos—presented potential embarrassment following a challenge by "The Guardian" newspaper to release the letters under the Freedom of Information Act 2000. In March 2015, the Supreme Court of the United Kingdom decided that the Prince's letters must be released. The letters were published by the Cabinet Office on 13 May 2015. Reaction to the memos upon their release was largely supportive of Charles, with little criticism of him. The memos were variously described in the press as "underwhelming" and "harmless" and that their release had "backfired on those who seek to belittle him", with reaction from the public also supportive.
