:Again more Pete twisting of facts. A head of state is by definition de jure. So adding in the word is as pointless as putting the word woman before queen, or writing The president who is President of France, etc. There is only one type of head of state. Wikipedia policy is against putting in unnecessary words that simply state what is implicit, and everyone knows to be implicit, in the term. 

 As to these 'number or errors', the only errors as in Pete's own interpretation of events and knowledge of constitutional law and terminology. Curiously, given that Pete thinks his arguments are so persuasive, not a solitary soul has come forward to agree with him, and people have been queuing through all the archives to disagree with him. If Pete is so convinced of his own knowledge he might like to give us his outline of his views, so we can get on with the voting.
