Footage showing Queen Elizabeth II giving the Nazi salute and doing a Scottish jig has been released by The Sun (a tabloid that has tits in it, for those not familiar with the British press).
She's the taller of the two girls, the other being her sister Princess Margaret. The lady on the left is the Queen Mum and the bloke on the right (in more ways than one) is the Queen's uncle, the future King Edward VIII.
It was made in 1933 and the Queen was 6 or 7 at the time.
