The Queen of the United Kingdom will visit Google's Westminster offices today and Google have marked the occasion with a special "Google doodle".
Normally reserved for holidays and anniversaries, the doodle will feature on the front page of Google UK. The image features the Queen's profile and a crown.
The Queen will meet competition winners and users of the Google's video site YouTube.
Last Christmas, the Queen launched a dedicated royal channel on YouTube. The channel has 54 royal videos and has been viewed 1.6 million times by internet users.
