London Mayor Boris Johnson has said that Prime Minister David Cameron was "only pretending" when he failed to correctly answer a question on the Magna Carta during an interview on the Late Show with David Letterman this week.
Speaking to LBC 97.3 Radio's Nick Ferrari, the Mayor, who has appeared on the programme himself, said:
I think he (Prime Minister David Cameron) was only pretending, I think he knew full well about the Magna Carta. It was a brilliant move in order to show his demotic credentials and to show he didn't have Latin bursting out of every orifice.
Ouch! David Cameron may regret ever appearing on the Late Show with David Letterman.
David Cameron was subjected to a quiz on British culture and history as he appeared on one of the US's most influential chat shows.
The Prime Minister has agreed to an interview with David Letterman - a host notorious for setting his own agenda. This could be interesting.
