"From The Official Website of the British Monarchy:

The Crown Estate is managed by an independent organisation, headed by a Board, and any profits from the Estate is paid every year to the Treasury for the benefit of all UK taxpayers. The Treasury is effectively the principle Government stakeholder and is kept informed of the estate's overall business plans and strategies.""

Oh, dear. When I'm researching, especially for authenticity, I lay quite a lot of weight on grammar, flow of text and the non-misuse of terms. .

Does that mean that using "principle" rather than "principal" is significant?
