Image caption Charlie Stayt and Louise Minchin interviewed Barbershopera on BBC Breakfast

The BBC has apologised after an image of Prince William with an obscene doodle drawn on his head was shown on BBC Breakfast.

It was spotted by viewers who then tweeted a freeze frame of the image.

A statement from the BBC said the image was shown "fleetingly" within a comedy promotional video.

"We failed to spot the offending material within it. We apologise for this," it said.

The video, provided by humorous barbershop group Barbershopera, was shown during a segment promoting their appearance on the programme.
