Penis-Headed Prince William Forces Apology From BBC

The BBC has apologised after it accidentally broadcast a picture of the Duke of Cambridge with a penis drawn on his head.

The blunder happened during BBC Breakfast when the programme showed a clip of a promotional video for the song I Could Have Married Kate by comedy singing group Barbershopera.

Eagle-eyed viewers took to Twitter with one, called @amandammorrell, tweeting: "Just watching BBC Breakfast and they showed a pic of prince William with a drawn on willy on his head".

Is that a dick I see on your head?

A spokeswoman for the BBC said: "This image was shown fleetingly within a comedy promotional video for Barbershopera, a humorous barbershop group, who were appearing later on in the programme.

"The material was provided by Barbershopera but we failed to spot the offending material within it. We apologise for this."

The song, about a lovelorn fictional former partner of the Duchess of Cambridge, includes the lines: "I'll be there, baby, on the day you marry and security won't notice me because I'll dress like Harry, and when Rowan gets things going I'll reveal myself before it's too late because it should be me who marries Kate."
