Every summer, The Queen holds garden parties at Buckingham Palace and the Palace of Holyroodhouse. 

During the annual garden party season, some 30,000 people spend a memorable afternoon taking tea on the lawns as Her Majesty and other members of the Royal Family circulate amongst the guests.

July's Focus looks back at this Royal institution with a gallery of images dating from the 1920s.
