Gordon Brown head of party, not head of state

Thanks to Justin Webb for this:

"Incidentally CNN described Gordon Brown as a "Head of State." This mistake - a common one - is part of the reason why Americans often think Brits are uncomfortably nasty to their prime ministers. To American eyes attacking them can sometimes seem unpatriotic - they do not realise that these figures represent a party not the state. Conversely we Brits forget sometimes that Obama and McCain are competing to become America's Queen."

Thoughts?
