Photographer Alison Jackson made her name after taking convincing spoof photos of celebrity lookalikes - from Princess Diana and the Beckhams to Tony Blair.

The photographer has now turned her hand to Opera, creating La Trashiata which features dopplegangers of Charles Saatchi and the Duke and Duchess of Cambridge, among others.

The show is making its debut at the 2014 Edinburgh festival

Alison joined BBC Breakfast to explain why she wanted to branch out to Opera.
