The BBC has apologised to the Queen for wrongly implying she walked out of a photoshoot with US photographer Annie Leibovitz during a documentary.

A trailer for the programme, unveiled on Wednesday, showed the Queen in an exchange with Leibovitz, followed by a clip of her apparently walking off.

The BBC said: “This was not the case and the actual sequence of events was misrepresented.”

The documentary, A Year With The Queen, will be shown later this year.

“The BBC would like to apologise to both the Queen and Annie Leibovitz for any upset this may have caused”, the corporation’s statement continued.

Photographer Annie Leibovitz is seen in the trailer telling the Queen she will look better without her tiara because ‘the Garter robe is so…’

Before she can say ‘extraordinary’, the Queen replies, pointing to what she is wearing: “Less dressy. What do you think this is?”

The clip then cuts to the Queen walking through the palace saying to her lady-in-waiting: “I’m not changing anything. I’ve had enough dressing like this, thank you very much,” implying she had stormed off from the portrait session.

But in fact, this clip was filmed before the photographs were taken.
