A girl was left 'crying with joy' after Kate Middleton picked her out from the crowd and placed her tribute to the Queen among a sea of flowers.
The newly titled Princess of Wales, 40, was at the Queen's Sandringham home looking at tributes and speaking to the thousands of people with her husband William.
Schoolgirl Elizabeth Sulkovska, was carrying bouquet and a corgi teddy and was invited to walk with the princess and place her personal tribute to the late monarch.
She welled up with tears as she remembered the personal moment: "I went with her to put the flowers and the corgi down.
Elizabeth said, "Where do you think we should lay the flowers?"
The schoolgirl replied: "We should put them there".'
Gregory Hill, her head teacher from Howard Junior School in King's Lynn, said "Elizabeth was overwhelmed, she cried with joy at being chosen. It's just a wonderful, amazing opportunity."
The teacher said the death of the Queen had 'touched a young generation.'
He said: "The older generation obviously knew the Queen for longer but young children that haven't experienced the Queen for long on the throne still are greatly moved by her passing, and really want to do their best to celebrate her life and legacy and never forget her."
The royal couple are expected to visit an army training centre in Surrey later where they will meet troops involved in arranging the Queen's funeral.
