David Cameron found wanting on British history by David Letterman
PM fairs badly in pop quiz on British history during interview with American talk-show host

British Prime Minister David Cameron has been found lacking in an impromptu quiz on his country's history by American talk-show host David Letterman.
Cameron, who was visiting New York to attend the UN General Assembly, joked that his failure to provide the answers had "ended his career".
Letterman stumped Cameron with questions about the composer of Rule Britannia (Thomas Arne set a 1740 poem by James Thomson, a Scot, to music) and the meaning of "Magna Carta", the name of the founding document of the nation's democracy (it means "Great Charter" in Latin).
"You've found me out," Cameron joked. "I've ended my career on your show tonight."
During the interview on CBS' popular Late Show with David Letterman, Cameron admitted that he was "not very popular at the moment".
"We have got this big budget deficit, so we have had to do a lot of cuts and we have made a lot of difficult decisions, so that makes you unpopular," the prime minister said.
