Moment magician stuns his assistant by proposing her on stage during the act

A magician pulled off the trick of his life when he conjured a diamond ring from a puff of smoke - and asked his assistant to marry him live on stage. The West End theatre audience gasped as stunned Emily Yarrow said the magic word: 'Yes!' Marc Oberon is a world champion magician who has been performing for decades, but he confessed this was the most nervous he had ever been. And Emily had no idea what was about to happen as they played out their signature mind-reading trick, involving her wearing a blindfold and miraculously guessing a series of objects held in Marc's hand.
