Is Cornwall a part of England?

Cornwall is administered as an English county. However Cornwall is actually a Duchy and a sovereign nation of Great Britain, it is just not recognised as so. Members of Parliament are subject to an injunction forbidding the topic from being raised in the House of Commons and attempts to make the true information on the constitutional position of Cornwall public, using the freedom of information act 2000 have been blocked, with the claim that it is "not in the public interest". Recent attempts within the European parliament and by Cornish activists to have the Cornish, recognised as a national minority, were blocked by the UK. Government.

Because the Duke of Cornwall (Charles Windsor, Prince of Wales) is the head of a sovereign nation of Great Britain he enjoys special powers within the constitution that include the power to veto government legislation, as reported by the Guardian Newspaper in 2011.
