Fluffing the Englishness test

So David Cameron appeared on the David Letterman show in the US and failed to get the questions right. I mean how many people can name the author of "Rule Britannia" or even the person who set it to music? But being unable to translate "Magna Carta"?

Seriously this is someone who was educated at Eton and then got a first at Brasenose, Oxford in Philosophy, Politics, and Economics and the Magna Carta didn't come up in any of that? It's not even hard Latin if you stop and think about it we use magna in such words as magnitude or magnanimous at the least a guess of 'big' would be close rather than the correct 'great'. Carta... perhaps slightly more difficult until you remember what it is - a charter.

Just embarrassing.
